Different length intake bolts???
 

:chevy:Okay I am replacing my intake gaskets on my 78 5.7L 350 motor, it has the stock intake manifold. I got the bolts mixed up and I am not sure where they go. I know there is 3 long bolts and 3 short bolts on the left side. The right side has 2 long bolts (which one of the long one goes through the bracket back by the distributor and four short bolts. My manual doesn't say anything about the location of them. :chevy:

Can you look at the intake and figure it out. What I mean is is there more material or a "step up" where certain longer bolts would go and likewise are there "recessed" holes that would require shorter. You can run them in and see if they bottom or not. I haven't looked at a stock manifold in awhile.
Good Luck

There are some intake holes that if along bolt is installed will lock down the pushrod. If memory serves its the holes around # 3,4,5,6 intake.
