compression and head? Before i get flamed, I have spent the last 2 days searching for an answer and have come up short.
I have a lq4 stock short block. I am thinking about putting a set of stock 706 heads with gm mls 6.0 gaskets on it(i have them laying around). By my figuring the compression will come out somewhere around 10.5 to 1. Does that look right to yall. Is there any reason why I could not use these heads?
The engine will be going in a s10 that is being built for a sport truck NOT a race truck. I do know that the heads are not the best choice. It is going to be more bark then bite.
Thanks for the help

It does, I didn't. I had them backwards. With a dished piston, 6.7cc's, results are below.
