440 source super stealth heads good or bad?

Why do they have to be good or bad? There is all kinds of stuff in between. Here is what I've discovered in my tests on the Super Stealth.

could be either or, good or bad shouldn't be the question. Where to purchase them and who to have do the assembly for you with the correct parts. We have bought a few sets of the stealth heads from this company with all made in the USA parts and assembled heads are affordable. here is the website for info. Best to call them and ask any questions you have. Good luck!

I just purchased a brand new set of 440 source stealth heads and they are very nice castings. The only issue I have run across so far is that no lube was used during assembly. Valve guides and keepers dry as a bone. The valves are not back cut but that is no big deal. I recommend that no matter what you purchase, tear them down and double check everything!

can anyone tell me which are the better casting #'s 906 or 346 ? thx

I like the 346s better because of the throat and bowl, but that's me. Casting wise - they're pretty close quality. If you want 906s and have a few to choose from, run the "F" versions.
