Pan head gasket seal?

Post Tue Sep 25, 2007 7:13 am

I heard of using studs and nuts instead of bolts to get a bit more pressure on the head gasket without stripping the inserts.
Anyone seen this done? Should be easy since the thread is common.
Any other sealing methods?
Yes, this is for a supercharger using stock barrels and heads.

Is stripping the problem or pulling the insert out of the alluminum? I'm no expert but more than 60-65 lbs. scares me. Mike

Let me re-phrase that.
With a stud, the entire 65 lbs. is applied to the clamping force, none of it is trying to broach out the insert threads.

How about shortening the barrel; anyone seen an FL barrel with the top 2 fins cut off?

How about building up the barrels and heads and machining spigots on them,along the lines of the DBD Goldstar?
That would take the strain off the head gasket some and you wouldn't need to over tighten the bolts/studs.

Not sure what you mean.
How different from the original spigot on the cylinder and receptacle in the head?
