Valve Clearance - Number of cylinders

I do number 1. If the valves are all the same height and the pistons/rods have been verified for deck clearance and I have too much clearance I just send it.

If it as close as I run mine (I think I’m .065 on the intake and .075 on the exhaust and the exhaust was dusting the carbon off the piston) then I check them all.

And I use clay and I don’t use checking springs. If you do, you will have more clearance than the light springs will say you do because all rockers (all good rockers I should say) have a higher than nominal ratio. This accounts for flex in the rocker.

I’m not a fan of running valves into pistons but I’m also not a fan of running too much clearance.

It hurts power.
