Default Re: Need some head clearance advice

Hi Russ. Thanks much for the reply. I had reviewed your excellent post showing how to clay the heads with a spacer of known thickness at each end of the head. I had planned to do this but thought I would see if the pistons/valves interfered using no gasket - as one of the barners stated if they don't hit with no gasket your good to go.

When I found the valves hitting I immediately concluded the chamber area over the valves should be taken down .050. That was a panic jump to a conclusion............

Your suggestion of proceeding with your method of claying is the logical next step. Knowing the exact clearance with a .050 spacer at each end will help determine the amount of alterations needed. I'll give it a try and post back what I found.

Much obliged
Bill
