Since I'm running the stock heads for the S10 for now I'm wanting to get them milled so I can get that little extra beef out of the motor. I've read all kinds of different stories on how much to mill etc. but am still confused a bit on how much to mill. I'd really like to run 10.5:1 CR. From plugging in data to some CR calculators it seems like I'd have to mill the heads down to a 53cc chamber to achieve 10.5, but is this possible? Also, what gaskets are yall running with aftermarket heads?

 

Anyone have any suggestions? I'm going to take the heads to the machine shop this afternoon or tomorrow.

Yea I figured I'll just mill them .030 and run stock gaskets. It should put me at/around 10.3:1

BTW matt, a nice big box just showed up at the shop with some LSx pacesetter's in them

 

yeah ! . . . a month later

 

werd, when you getting the L92 stuff in?
