Hey guys!

Just got a set of bbk shorty headers. Which size header bolts do I need? Im going with the stage 8 locking set. The stock bolts are 3/4" but the flange on the bbk's are thicker, would the 1" be ok?

93 Gt stock 302

Thank u!

Joe

How thick is the header flange?
How deep is the header bolt hole in the head?
Those two measurement will give you an answer to how long the header bolt should be.

I have 1” bolts with my JBA headers. The 3/4” were too short with the thicker flange.

I previously had BBk headers. Let me go look at what I used.

"...get 1" bolts and remflex gaskets...."
thats the shinny silver gasket, not the dull grey?
I got both sitting out of the way w/o their regular packaging
and forgot what I have. All I remember is one was way better...
