When I called fel-pro they had no idea what I was talking about. (though it's likely because I wasn't talking to the right person, he wouldn't direct me to anyone else)

I ended up buying a few sets from Cometic.

Cometic has them but you will need to call for the part number. They have a left and right as they are different.

I called Cometic Thursday and they list around $90 each. I would believe they could be ordered from a vendor for less money. SDPC is one of many that handle them. The part numbers below are for .040" crush thickness.

Left, P/N H2570SP1040S
Right P/N H2569SP1040S

WOW I haven't heard that out of the Cometic's. I do know however that if you don't surface the deck and heads properly there may be a problem. You have to machine the surface's with at least a 50 RA surface finish or finer or you may have a problem.

My cometics are perfect, so far, after one year and 25,000 miles. All I did was hand sand the block surface with sand paper and my head guy resurfaced my heads.
