I'm looking at decking my block .020" and my heads .010" for a high compression build, but I only have .023" of clearance between the top of the piston and the headgasket.
If I put in EA82 SPFI pistons, and shave off the .020", will I run into issues with hitting the piston on the cylinder head?
And I don't want to shave off too much from the head as I don't want to make it so thin that I have warp issues.
So, my official question is, what is the height difference between an EA82 SPFI piston and an EA81 NA piston?
This is obviously measured from the top of the piston to the pin, as that is the distance I'm concerned with.
If the piston height is too much, would it be better to convert it to .015" off both sides or just go with .010" off the block and .020" off the head?
The head seems to have a lot more material I could shave off than the block at this point.
