Carefully check your intake gaskets first, then if they look good check the intake runners for signs of oil or coolant. No need to bust the head seal if your intake gaskets are to blame. If you decide to change these first, do not fret if you see some white smoke on start up. Run the engine at 2,500 RPM at least 4-5 minutes to burn off the coolant trapped in your ring lands. When it all burns off. You might find your head gaskets are ok.
By the way, buy a compression testor first and let me know what you get cylinder to cylinder. You should have at least 140 lbs everywhere. If one cylinder is low, like a 100 to 115 lb reading, then at least you know which head to pull.
If you change head gaskets. There are some ultra cool graphite head gaskets available. I bought mine from Aldridge motorsports 503-284-8484. Even with detonation bad enough to break 4 of my 8 chrome moly rings, they kept their seal!!!!
