Please if anybody else has the torque specs for other relevant parts please let me know and i'll add them.
If something is not right please let me know, because i don't have a FSM i found the info through searches.
A couple of parts are missing the sequences, if somebody knows the let me know so i can add them.
I hope this is useful to some people

thank you

no problem, its definetly good info to find all in one place, i just knew it was two 90's being ive done soo many of these. didnt want false info to be out there. Good job though. Thanks

Please also make a note guys that when putting the headbolts in please dip them in oil before install.

Anybody know what size alan wrench are the headbolts?

Its a 10

Is it possible to add recommended torque specs for aftermarket bolts? Especially ARP head/main studs and rod bolts. Also other manufacturer specs are usefull.

Has anyone ever checked and see what the actual final torque spec # of the headbolts are.

Just curious.
