Static Compression is currently 8.5:1 but I would like to raise it to 9.5:1 by milling the heads.
I know it is best to raise the compression by buying custom pistons to lose the 0.040 in the hole, but engine is in the car now and the pistons are $$.
I cannot do a compression test because the heads are not yet on.
