I have stock 88 heads but I did have some work done as in ported and milled 0.20
I put in andrews tw31 cams. And to realy have these cams work gotta have 9.8 10.5:1 compression. I have 1550 flat top pistons. Just seems that it don't have high enuff compression. What else could I do to bump the compression up a little more to reach my goal. And another thing what would be the cc on these heads.
