Ram Air IV head bolts
Anybody have or use the new ram air 4 head bolts yet - i bought a set and the seem to be the right length but they do not have the shoulder under the hex head to keep them straight in the hole like the original. They walk around a bit until you get them tight - should i be concerned. They came from parts place and i hear ames has the same ones.

John...
we have a set on Kevin's RAIV, but have not run the engine yet. I don't forsee any issues, but I'd hate to be the one that finds out, so let us know how yours do, OK? lol Ron

I don't think i want to chance it - the shoulder aligns the top of the bolt in the hole - with out it they are all over the place. The bolt also has a built in machined surface at the bottom of the hex - typical of bolts so that the hex does not dig into the mating surface and while the new bolts have it the hex corners are formed over this detail and the bolt hex head dig into the metal. Just not like the originals. Anybody run an engine with these bolts in it. Thats all i need a head gasket problem to add to all the others.

no washers? try using washers from ARP may not be correct but no shoulder issues. i would put a dab of antiseeze or something under the head of the bolts to reduce friction. i have an original set of IV head bolts somewhere but i will need them
