You're really going to f up your head if you mill it enough to get 2 points of compression.

 

Actually I believe your compression by default is closer to 10.6:1..

and no, I honestly doubt you could mill enough of your head to bump up compression by THAT much..

yea 10.6 my fault.. i though that it was too much to mill... ty

 

i think 11.5 is the max for just milling the head.

 

I would stay safe and reliabe and get pistons... supposedly the mahle golds I think can be run without sleeving

 

"Hello Piston"

"Hello Valve"

 

lol

 

lol yeah mill the head for 12.5:1.....lol....and get a custom timing belt while youre at it
