Ok, since I have to replace the headgasket (possibly the head) I figured why not get a couple extra ponies while the heads off.

So, I'm wanting to figure out what my final CR will be after the head is shaved 25 thousandths + the 2 layer headgasket.

The above link is to the spoon gasket which states it raises the CR 0.2.
So that puts me at 10.2:1 CR w/just the headgasket.
Now, with the head shaved 25 thousandths + the 2 layer gasket, what will it be?

Ive tried to do the calculations, but I con't understand on how to get the piston to deck height from the gasket.
Any help? Since it's a technical question and isn't dealing w/an intake or exhaust, I prob. won't get many replies.

In addition, I read in a thread on team-Integra that shaving the head 25 thousandths on a GSR raises the CR 0.7-0.8:1. So does that mean if I did the 2 layer gasket that I'd be 10.9-11.0:1?

 

Wow... I was searching abotu head gaskets and stumbled upon a thread I started.


And I'd still like to know the answer!!
