I recently was given a ZZ4 350 Chevy small block for that came out of an airboat and the problem they had was high pressure in the day tank of the radiator.I diagnosed the problem as the head gaskets.They were replaced and the heads shaved prior to my getting the motor but I found that the heads were not properly tightened.I was given values of 75 Ft.Lbs. on the long bolts and 65 Ft.Lbs. on the short bolts but I don't agree with the values due to these being the aluminum heads.The heads are the same as a 1987-1991 Corvette L98 engine.Unfortunately I skip over those years in all of my books.Does someone have the actual torque values for these heads?I think they should be a degree torque instead of a direct torque but I may be wrong.
Thanks for any help.

I found my own answer.It is a straight torque and it's
65 Ft.Lbs. on the long and medium bolts
60 Ft.Lbs. on the short bolts
Thanks for looking!

Make sure to use NEW head bolts.
