I put new head gaskets on my 460. I have not finished putting the engine back together. I still have to do the exhaust, intake, carb, distributor, steering pump. I did a compression test and still have numbers of 90 lbs. Is this accurate and I have other problems or do I need to put the engine all the way together and run it before I get accurate numbers?

How many miles are on motor? 82' motors are pretty low compression, you could cut heads down maybe 30 thousands to raise compression!

That won't fix bad rings... That well just raise the Compression ratio NOT the compression and could cause other problems like having to run higher test fuel Like race fuel depending on how much you mill the heads. Ether way low compression test that raises with a shot of oil is 90% bad rings.

good luck take care be safe
