question about finding compression Ok I recently installed 241 casting heads that were milled .042 I have a .051 mls head gasket on as well. I am just trying to figure out if what my compression ration would be with these heads.
If you know the formula that would be greatly appreciated, I welcome any and all responses.

Thanks yeah I don't know what I was thinking.. my brain has been deerrr mode after the whole thing i got it done in about 4 days all in my garage with hand tools and **** breaking left and right... mainly a rocker arm bolt and even the crank pulley (harmonic balancer) I broke one of the tabs off that you grab onto with the puller.
After spending about 4 hours going and picking up random parts here and there got head/cam headers y pipe and everything done. Not bad for a first timer and the car starts up and drives with some adjustment of the idle screw.

On a stock LS1 short-block, you'll be at about 11.2-11.3:1 static compression (assuming pistons the average of .007" out of the hole and 60-61cc chambers). Hope that helps!
