I am wanting to change out my oil pan gasket. It's a 79 350. I have heard good things about the Fel-Pro one piece gasket and thought about trying it. Or is there something better? Also I was wanting to use ARP studs instead of the stock bolts for ease of lining up the oil pan. And finally, I was going to replace my oil pump at the same time since I have low oil pressure after the engine gets hot. Does anyone have a suggestion about which oil pump to use. The engine has 90,000 miles on it and is still untouched.
