This should be the correct one for the upper to lower mating surface...

http://www.summitracing.com/parts/HLY-108-80/

The lower to heads will be one of many...I used Mr Gasket 5834, and Fel-Pro 1250 with great success...

Ford racing sells several under their moniker as well-they're all Fel-Pros...sometimes cheaper. Summit sells everything you need for this particular operation...

I would match the head gasket to the other side if your only pulling one head....stock replacement cyl head gasket would be a Fel-Pro 8548-pt2 or an upgraded graphite gasket is 9333. The holley number listed above is correct for upper to lower intake, although the Holley lower is closer to a Fel-Pro 1262 (intake to head)

Really? I didn't think the ports were that big...hmm! I recall reading a while back, the upper to lower gasket on the Holley intake is/was the same as the EFI truck intake-any truth to that one? I never messed with the systemax pieces...

The holley lower has went through a few changes it may be a little closer to a 1250 now, but I find them to be as tall as a 1262, but maybe not as wide...running the 1262 wont hurt a thing.

Comparing the Holley lower to a EFI truck intake is life comparing a F350 to a Smart Car The upper to lower is near identical gasket wise
