Without a compression check its hard to say, and also as stated before 90FTLB's is wayyy to tight. remember our heads are aluminum! they dont need much to seat, and to much more will ruin the head, the material is to soft and the studs will permently score the head and result in impropper torque readings from then on so be careful. there is no need to over TQ the studs. if its leaking its not going to help anything by over TQ'ing things.

BTW, make sure you grind down the dowl pins if your removing the head again. alot of times not doing this on a head that has been milled will result in the corners of the head sitting up due to the dowls bottoming out, thus leading to oil leakage!
