ok thanks and what about the pistons, what type of valve reliefs are they 5cc or what?
ALso do you know the deck height of a stock block and far in the hole the pistons are?
im trying to input numbers in to find out my compression and i want to make sure of them.
its a stock block with 57cc heads that were milled and a .026 gasket. Do you know what it might be?

I have had a shop tell me I had 58cc heads. I had to show him the stats to change his mind. He insisted on cc'ing the heads, refused to believe the documentation. 56-55cc is what we got on 1993 LT1 heads. It seems to vary from head to head, possibly from year to year. I don't know where so many are getting 58cc. Possibly the #s changed from year to year? Does it possibly have to do with the valves?
I would like to know where the 58cc number is coming from.
