Subject: RE:Can I rant for a moment....... by dan0617 on 2008/2/26 16:09:31 Most of those guys don't understand the whole velocity thing with heads. They are all tied up with brand name. AFR's might be the best (might not either) out of the box, but no matter what the name on the head it needs to be sized to match the cam, intake, converter, gears, etc. That is MUCH more important than the name on the head. Take the best flowing 220CC runner AFR heads and put them on with the stock cam and TPI and you will likely be slower than you were stock. SO, you could argue that the stock heads are better than AFR, right? I know ol'RJ had AFR's and got better results with ported Dart heads. I know Vic'89 is running some seriously fast times with reworked stock 113 casting heads. I seriously doubt he would do any better with AFR's with his combo. And it is possible he would do worse. I chose reworked 113's ported, coated, and bigger vavles because I got them for $500 used, assembled and shipped. Then I sold my stock 113 heads for $300. So for $200 I got heads reworked by Precision Motorsports that have about 3000 miles on them and they still look and work like they were redone yesterday. Again, it is a port velocity thing with these heads, and having a cam and intake to maximize that. You gave the guy the right advice. My advice would have been for him to decide exactly what he wants to use the car for, find a head size category to fit that use, shop the used market if he is on a budget, then make sure he swaps the cam and possibly intake to match those heads. Also consider the converter and gears. Big cam and heads and miniram need high stalls and low gears to work best. Brand name is not that critical it is about the least important thing, size and a good port job is. You gave him the right advice for the info you had on his car, future setup, budget, etc. Don't sweat the bashers. |
