So you say Liffter setup B?
If the lifters keep the valves from closing completely during pump up due to high revving the pre load is used up and why are these valve not closing? Is this because of the additional length of the hot valves?
I'm try to find out why one should maintain such a high clearance .100" when the totall expantion due to heat is not that high. I don't know what lash is used when using solid lifters.
What are your thought about a safe valve-piston clearance of < .100" ?
