Yeah, that'll burn off too. It did on mine even with the "high temp header" paint. Well damn, maybe I won't waste the time. That paint isn't cheap either. $9 a can. Spent a couple of hours in the garage last night and all I accomplished was getting the intake manifold cleaned up. I was reading on yellow bullet last night about some header paint. Some guys have used the VHT where you bake it off the car through several heat cycles and they say it works well. Also some recommended BBQ paint, although you might need to reapply yearly. I'd probably still paint it just to help prevent corrosion on the lower parts that might not get as hot. As far as the tall VCs, I've seen guys cut out under the bracket and weld the piece back in upside down. Matthew

I looked into having them coated but the only places I found are in VA or SC..so much for Nascar country I don't know how much I will get to work on it this weekend since we are leaving out Sunday morning. Hoping to atleast get the block surface cleaned up and replace the connectors that I bought for the MAP, TPS and IAC. Might get to put the heads on Wednesday night.

I got the dumbass award for only ordering 1 head gasket...thought they came in a set. Sort of worried about using the 1094's on the non-machined block.

As long as all is straight you should be fine. If it's regarding piston depth, stock piston height is more than sufficient to prevent any interference. Matthew

I just can't afford to have the head gasket fail and cause bigger problems. I should get a slight bump on comp with the 1010's. Again it's not like I track the car. I ended up painting the headers just for the hell of it. They look so nice I hate to put them on the car.

[IMG]http://i149.photobucket.com/albums/s46/kresge1975/1990%20Corvette/SU1HMDAxMzYtMjAxMTAyMjMtMjAxMC5qcGc.jpg[/IMG] I also placed the valve cover on to check wiper motor clearance. sorry for the crappy pic but you get the idea [IMG]http://i149.photobucket.com/albums/s46/kresge1975/1990%20Corvette/SU1HMDAxNDAtMjAxMTAyMjMtMjEwNC5qcGc.jpg[/IMG]

Elite Guru Westmont, Il. 2632 Posts Member since: 2008/9/28 12:47	Interesting. I have read that the self aligning rockers were employed as a cost saving measure (no hardened pushrods or guide plates). Also, some aftermarket heads (AFR for one) require the non-self aligning ones. I don't really know which are better. I suspect the non-aligning would be more bullet proof. What brand are your rockers? The color looks like Crane.

Elite Guru High Point, NC 1440 Posts Member since: 2010/6/18 12:27	From what I read most engine builders will not use the self-aligning. I am not an engine builder but I did research and everything I read was to go non self aligning. They are Wysco.. Crane knock-offs. Price was right. I had my machinist clean them up and we looked them over real good. Don't seem to be any apparent issues and they have a 5 year warranty. I soaked them in oil for about a week too.

Elite Guru High Point, NC 1440 Posts Member since: 2010/6/18 12:27	Well, since I have no pushrods I couldn't get anything done this weekend. Sucks too because it was so nice out. Anyway, I guess the all black intake is out because of the shiney new valve covers. I dread the thought of sanding all of the paint off the runners...what a pain. I also noticed that the inside of my plenum is coated with oil. I don't know what could cause that. I must have botched something when I did the intake manifold the first time.

Webmaster SW Chicago Burbs 22803 Posts Member since: 2008/1/7 0:00	Jeff, I found some light oil deposit in my manifold when I took it apart this weekend, too. I'm figuring it's from the PCV. Unless it's a huge amount of oil I wouldn't be super concerned.

Elite Guru High Point, NC 1440 Posts Member since: 2010/6/18 12:27	I am going to clean it up tonight, get the oil out and take my time putting it back together. I don't remember there being any oil in there when I took it apart to do the IM gasket a month or two ago. I am seriously wondering if the leak in the rear of the china wall could cause some sort of funky vacuum that pulled the oil up into there and caused the oil pushing out of the VC's

Guru Lawrenceville Ga 718 Posts Member since: 2007/12/30 0:00	Are you using aftermarket valve covers? Some of those don't have the baffle and this will cause the PFC valve to actually suck oil fumes into the plenum. Dosen't take long for a coating of oil to cover the inside of plenum and even lower intake. Joel

Elite Guru High Point, NC 1440 Posts Member since: 2010/6/18 12:27	I adjusted the valve lash last night. I used the method that Joe C on the other forum wrote and a few other members supported. I haven't done valve lash but one other time and that was on Dad's engine when we had it on the stand so I'm a little nervous. There are so many different techniques to doing it. Got the intake manifold on and torqued down too. I put a healthy dose of Right Stuff on the china walls so hopefully it doesn't leak this time. I am going to have to shave the posts on my new valve covers to fit in between the rockers.

Elite Guru High Point, NC 1440 Posts Member since: 2010/6/18 12:27	Re-adjusted the valves last night. Kind of glad I did since I realized that one of the VC's need a little trimming on the post. The post was rubbing against the rockers. Not sure what the covers are made of but it's a pain to file down by hand and ruins dremel sanding drums almost instantly. Got the oil filled. Put the 4 passenger side plugs in and then started to put the headers on and put a 3" cut on the top of my head on the fender. I decided that it was time to quit at that point.

It is down on all 4's now. Fluids are topped off, timing is set. Oil pressure reading at 80 cold. I let it warm up a couple of times to try to cycle the header paint. Now I really can't wait for 5 o'clock tomorrow!!!! Thank you all for your help and support. And for answering my dumbass questions.

I am going to invest in an Moates cable and datamaster next so maybe I can get Mick or someone to do a mail order tune for me and get rid of that EGR code 32.

Still need to get exhaust leak at the cat fixed. I posted a vid in the other C4 section. I had to re-adjust the passenger side valves this morning. Think I still need to do the drivers side again.

Scrubbed them with simple green wire brushed them really well took a heat gun and got them warm sprayed them with 3 medium coats using the heat gun in between coats to help "set" the paint. Then they sat in the trunk of my other car for almost 2 weeks.
