Compression change with head gasket

moving to a larger blower so going from a MLS style gasket to a copper with o-ringed block/heads. I’m currently at 10.6:1 compression running a 4.584 bore .053 compressed MLS gasket with a 14.50 cc compressed volume. The copper gaskets come in a 4.57 bore .050 thick (13.795 cc) or .060 thick (17.106 cc) compressed. Assuming the .050 was the way to go just not sure how much that raises my compression...didn’t know if there was a formula to figure it out. On a big block Chevy with 4.525 bore and 4.25 stroke.

 

,010 gasket changes compression roughly .25 of a point

 

I always used .010 of gamete was .3 of ratio. According to one of the top engine builders in Nhra.

 

It depends on the bore and stroke of the engine in question....
In this case .003 thinner gasket will not change CAR enough to matter

 

Try this....

We need to know your head chamber volume and piston dome volume?
