1) Is there anyway of identifying the compression ratio of these pistons ? The AE no.is 6120\T 88.In researching this I understand that the AR original piston was 9:1 but I've read that current standard pistons are 9.5:1.
2) So once I get that settled I'm thinking that I would like to get my CR up a bit to work with my S cams.I would do this by having the heads shaved a bit.So the question is how much would I need to remove to get somewhere near 10:1 - obviously that depends on the ratio produced by my new pistons.
Needless to say I'm doing this on the cheap otherwise I would have gone out and bought some 10.5:1 pistons and be done with it,but the wife is keeping a close eye on me these days

If Jim K's new V6 book was out I'm sure all these questions would be answered
