I got the engine apart, and will probaly put it back together tommorow. I am using the steel shim style gaskets, do I use copper sealant or not? Also, do I use thread sealant on all head bolts? Do I attempt to clean up the head, intake area to include the area below the valley pan gasket or is it just wasting my time? If so, how should I clean it? Sorry for so many questions, I just want to make sure I get this right the first time, my knuckes are bleeding on both hands
