Subject: Re: Cold compression test? by rklessdriver on 2011/2/2 14:49:44 JeffK- With the stock 113 heads... I suggest you have the machine shop cut a 3 angle valve job and then back cut the factory intake valves with a 30* cut. I personally wouldn't spend the $$$ to buy new stainless valves unless your factory valves are unuseable. If you do happen to need valves, buy them from Competition Products. Summit is getting about $8.00 each for their branded imported stainless valves.... which are either Martin Wells, Manley or SI mfgr. You can buy the same valve from CP for $6.00 each. These are what you will need. http://www.competitionproducts.com/St ... ntake/productinfo/I2552P/ http://www.competitionproducts.com/St ... xhaust/productinfo/E2809/ However if you buy them in a set of 16... You only pay $4.37 each. http://www.competitionproducts.com/St ... 32-Stem/productinfo/8430/ If you go with roller rockers you should check the valve train geometry. You may need a different length pushrod. If you do plan to upgrade the camshaft or go with 1.6 rockers make sure you buy and have the machine shop install the correct valve springs, locks and retainers. They will also have to cut the valve guide on the cyl heads down for clearance. Will |
