Intake manifold bolt length TBI chevy

Hello members I have a 1989 K5 Blazer 350 TBI engine. Iím installing new intake gaskets and replacing the bolts. What is the Max length of the intake bolts I can use. I know if there too long they interfere with pushrods. Some of the old ones look short and are corroded. Thanks for any assistance.

Positive you don't want any 3/8-16 bolt longer that 1 1/4" length.
