Re: straight 6 intake exhaust clamp?
If you cannot find any, one can be made from a piece of 1/2" thick bar stock. Max torque on those is only 30 lb-ft. Have done it more than once.

Re: straight 6 intake exhaust clamp?
Do you have all the clamps except one long style? below are a couple of old threads about the clamps. I wouldn't bother replacing any of the missing bolts. NAPA should have studs that fit for a much easier installation. There should be two studs now in the 3rd hole, in from each end. Head rebuilders often remove them and don't replace.

Re: straight 6 intake exhaust clamp?
I have used the high-grade alloy steel pivot ball -- flipped around -- to secure the end bolts on L6 headers. Studs hold the stock manifold in that set up.
