When you add P29's without changing headgasket thickness, bore, and without milling the block and head, you C/R should be 12.65:1, which is a little on the high side. Probably wouldn't be the greatest DD either. I would bump it down to around 12.0:1 by switching to a Z6 head or getting a thicker head gasket. One thats around .050 in. And as stated before, if you do decide to do this, do a complete rebuild.
Thank you for clearing that up ROb. Yeah the calculator that I used said it would be 13.65:1 I guess I put in a wrong number somewhere. Well thanks for all of the input guys I most liking wont be putting those in anytime soon, that is until I get get another block.
