piston to valve clearance

piston to valve clearance

Now , Is this right ????? Heads nipped up (not torqued) on OEM gasket which measured around .087 thick piston TDC on compression stroke, valves on # 1 cylinder held in place with test springs. Push down on rocker by hand and I get around .090 of travel before contact. Now if the OEM gasket has...

I have that thanks. Thats where I got the .185 (max) measurement. Oh btw my pushrods are .030 over not .060. Now that .185 Max so what Im getting is OK . Im assuming that if you were up near the max your valve train would be getting noisy.. Also I have noticed that there is some preload on the...

Comp 910 valve spring height

Just need some advise - Should I be happy with a install height of 1.750 = 113lbs or go for 1.700 = 134lbs 1.700 would mean I need to get shims cause I have enough to achieve 1.750 One other thing, Do I put the shim under the seal or on top ??

update.- Heads are going back to get valve seat inserts installed. I have made a deal for supply and fit which Im happy with. This will get the valve recess back to spec across all valves and also bring the preload down so I wont have to shim the rocker pedestal. If I paid more attention to...

cleaned up the pocket and runners thats all. And the valve to piston contact was due to preload being to high. The pushrods I have are Smith bro .83 wall and +.030 length. I have a set of EOM as well which had to much preload as well. If anything my pushrods should be -.030 or there abouts. Just...
