I mis-understood the instructions and torqued all the 7/16 head bolts to 85lbsft. I believe they were refering to cast iron with 30wt oil now not aluminum. I know the manual says one torque figure, AFR says 70/80 lbft., and ARP says 60lbft.
So do I:
a - leave them alone?
B - loosen and retorque bolts?
c - buy new head gaskets and do it over?

When doing my head studs I did same thing, torqued them to the 30wt oil specs but used ARP lube. I left them alone and haven't had any problems...

I don't feel so bad now that I know someone else made this mistake.
