174/177 supercharged small block, where to start?

Looks good! Are you using studs for blower body to intake?
Unfortunately, no. The studs supplied with this kit were too short, and the nut only went on about half, with just barely a comfortable amount of thread engagement in the manifold, before I ran out of thread… So longer Allen head bolts were used.
I’d prefer studs, who can custom make me a set? Last I checked with ARP, they wanted a THOUSAND dollars…for 4 studs…..LOL.
