regarding Bob's performance intake mods:

I was wondering what anyone (especially Bob L.) thought about using west system epoxy thickened with filler (maybe their aluminum powder filler) instead of marine-tex or similar putty-type epoxy coated with the unthickened west system stuff as he describes in the article...
in their product literature, west system says you can thicken their epoxy to the consistency of peanut butter...

would this application be impervious to the heat and fuel in the intake??

is there anyreason to not use the west system epoxy all the way through??

also, I was wondering if people fill the bolt holes with epoxy and then grind out the manifold, or fill the holes after breaking through

ok, that was very helpful... I did notice that for the plenum ramp you used an aluminum plate instead of epoxy, but I thought there was still epoxy in the four intake-to-exhaust bolt holes...

so when preparing a manifold yourself do you just weld up a bunch of excess material around the carb pad and in the bolt holes and then start grinding away???

also, how do you ensure the bolt holes are filled?? is this something most aluminum welders can do?? (i don't know anything about welding)
