6 banger gasket kits?

[Americanrider]

I finally got to working on my 70 GMC in an attempt to cure the exhaust leak at the header pipe. I snapped off one the studs when removing the collar.... oh well I was ready for that. I pulled the headers down from the rafters and off came the hood, the carb & intake. I did a test fit and it looks like I'm going to have to grind a little off the drivers motor mount. So I went shopping for a gasket set and found Hooker makes a true header gasket to fit the I-250CID but nobody has a real intake gasket to match. I was hoping to find a copper gasket to help with any leakage problems.

Any Vendors out there carry such a set of Intake & Exhaust or should I just use the single piece stock gasket and hope for the best? I might pull the motor and cure a few minor oil leaks while I'm at it. So if anyone knows of a parts source for the whole gasket kits for cheap post up a link. The going price around here is about 60-70 bucks for the whole felpro kit.
