Default Crank or heads first
I am gonna put my heads on and on the ls1howto site it says to put the crank on first. Is that true or needed? Also someone told me I should have engine at TDC when I put on the crank, is that true?

Doesnt matter either way, the crank pulley is not keyed and has no timing marks so you can do either first.
