H.E.

I've done this job more than once.

The critical measurement on the head is side to side rather than the length. They all seem to bow a little down the length but that straightens out somewhat if it is not too much.

Chase the threads on the studs and the nuts. if you have time , order hardened washers from Mc Master or someplace, this will make the torque hold better. I have also read about finishing the bottom of the nuts with about #300 or so sandpaper to make friction on the bottom of the nuts consistent .

Torque according to specs in stages.. Torque hot after first running the engine and then at may be 50 miles , 100 miles and 500, or something like that . The long heads take a number of tightenings to settle.

Best
