Quote: I think this was my problem. The last kit I pirchased had the tabs seperate from the main seal. Can't remember what company. I didn't cut them off though. I have the new main seal which are the brown seals in this pic. They are Fel-pro #40181. They came with no tabs on them and no tabs in the box.
I have had great luck using the 318 magnum 1 piece gasket. In all cases you have to modify the oil pan to take the tab bump out of the pan rails so the gasket matches the pan. Easy to do with any hammer and dolly, and a welder. None of the 340s or 318s I built have leaked. I with MrP and never stagger the seal. Just made a headache for me in the past.
I also have a high oil psi engine, but no leaks at all. SOMEDAY ill shimm the pump, but for now Im gonna just run 10w40 oil.
