1.2mm or 2mm head gasket?

[holdbrooks]

I just read the head shaving thread and searched around a bit, but was wondering what you guys thought about it all.

I just picked up my motor from the machine shop and they took about 0.014 off of the the head and block combined. I know that stock is 1.37mm and to keep stock compression I would need a 1.73mm hg. so my question is should I undersize or oversize the thickness of the hg? The Block has also been bored 40 over and using reconditioned rods (slightly shorter I presume).

I would thing a slightly higher comp ratio would be better on a n/a than a lower one what are your thoughts?

What happened to the motor in the silver car with the Probes?

Andrew, you can order a cometic hg any thickness that you want.

Gotcha. Like Jay said, Cometics come in any size you want, and like Greg said, compression is better, but I don't know that you'd really see any significant performance difference.

i dont exactly remember what size gasket i used or anything but i know i went with a little higher compression and it made a worthy difference in performance id go compression style
