Valve to Piston clearance
Hi!
I'm building currently a B18C5 engine with 11.5:1 Pistons and Skunk2 Stg 2 Cams.
The head is slightly modified.
How much clearance should be between the Pistons and the Valves to run the engine save?
TIA
Doc

Re: Valve to Piston clearance (Rocket)
I had these cams and because I did not clay the block I ended up with 7 bent valves and 1 broke one that went thru the piston and smashed the combustion chamber of my beautiful ported head. Better safe than sorry
