243 heads on a 4.060

Bought a fresh machined .060 over lq4, h beam rods, and pistons off here. Decided to go with an aluminum 5.3 for my project. Trying to resell the lq4 stuff locally, and its not gone yet. Got a set of 243's on trade for other parts....

So what about 243's on the .060 over block if I put it together for who knows what project???

OK, thanks! Now need something to put it in. My 355k mile 4.8 crusty express van needs replacing......

Do you know what the compression ratio was with the cp pistons and the 243's? I havent even unwrapped the pallet yet....
