Okay, like I said I have 2 engines. The one for sure is a 77 block which is in the car. my spare thought it was a 76 ran the numbers to the chart, found the number just above the water pump, #395558 2 and the heads are #8 SWTF??? Any ideas guys

If the heads are original it could be any year from a 1973-76ish? You need to check the vin number stamped in it. The first digit will be a 3 for Oldsmobile, the second will be the year of the car it came in. 3=1973, 4=1974, etc. If your not sure where the vin is stamped check this thread:

at first I had thought it was a 76 block,got the numbers from the block, looked on line most places said it was around 70'ish block.Thats why I was a little. Ran the second set of numbers you told me and that makes more sense. THANKS

I assume too much, my bad. The reason for cutting .015 and using a .028 gasket is to keep the price down. Speed Pros generally sit .025 +/- down, so, cutting .015 off the deck that makes it .010 down plus the .028 gasket gives you optimum piston to head, right around .040. You could zero deck and use a .040 gasket, but that is just an extra cut of the top of the block.
Here is a calculator, start using it,
