Piston To Valve Clearance??
Does anyone know what piston to valve clearance at overlap you would find in a STK 9.8:1 Euro SC? Exhaust and intake ?

My U.S. 9.3 engine had about 2.5mm clearance.

If you have 0.090" clearance your good to go.

If this is a project underway, BE SURE to check clearances all over the combustion chamber, not just where the valves might make contact. Take a look at this...Head gaskets destroyed but why? 74 2.7 911.
