hello everybody.

im rebuilding a b16a2 for boost. (9.1 pistons/eagle rods arp studs ect ect)

now, i checked the head surface with a stright edge ruler and a feeler gauge all around it horizontal/vertical and diagonal ,even the thinest leaf (005 i think) didnt got under the ruler, so there is no clearance at all .

but a few friends told me that i should mill it anyway and now im fustrated.


what should i do?


thanks.

 

If it is flat, then why in teh hell would you want to mill it? Especially when you are going to boost it. It already has a 10:1 compression ratio. milling it will make it higher and more prone to detonation. do not mill it unless it needs to be and you are going all motor.
