IMM Engines 408 build

My mellings went in with EQ heads in place, but i don't know if there is enough room if a thin gasket is used or the block is decked more than a cleanup.
The only way to set preload with adjustable rockers perfectly is to do it with the lifters empty of oil. I went through the firing order and tightened them till my fingers couldn't rotate the pushrod, then backed them off a certain amount.
