2.7 rebuild
 
The engine is almost done, I was doing a piston to valve clearance check:
I get 1,1/2 turns on No.4 exhaust adjustment screw.

Cams are 2.55 grind, pistons CIS, case and heads have been machined.

Do I need to tear this side of the motor down ?

Let me know what you think!

The thread pitch is 1mm on the adjusting screw.

Understood, so the question is will I have a problem with 1.5 mm clearance on the exhaust valve?
