What are the torque down specs (PSI) for an aluminum intake to cast heads per bolt on a chevy 350. And what is the tighten down sequence...if anyone knows?

Thanks in advance,
Anthony

Same as cast iron 35 lb ft.

Start in the center and work your way out.
9 5 1 3 7 11
10 6 2 4 8 12

Do not go to max torque on first pass.
Ex.
15 lb ft.
then
25
then
35

That will take it down nice and slow and you
wont break the ear off the end.

I know you know this already, but, get a shop manual.
I got one for early A bodies and have referenced it many,many times.
Mine is a Hanes.
