old heads on new block help!

Okay... So I have not built engines before but I do know a bit, I was looking for simple tips to get this right. Like do I need to lube the cam shaft further than the the original rebuild did, rocker arm adj. , issues that may arise match newer reman. block to older heads.... Somehow I thought this was a forum for all to learn and share. If you do not want to waste your time answering than don't.. And I do have the books and I have read but they really do not cover my particular issue..
