What is a “HEMI Big Gas Head”?
Think of it as a Hellcat head with a 6.4 intake manifold bolt pattern....etc.


Thanks gents! I now know all I need to know about BGE heads. It seems like they are the pick of the litter in factory Gen 3 heads. 356-T6 is a huge improvement.

It's pretty impressive that a gas powered NA production truck has hollow stem intakes and sodium filled exhaust valves. One would have to think that the valves are a stainless alloy. My guess would be a 21-4N, which would assist in the "durability in a heavy duty environment" parameter. If this paragraph proves to be in error, I'll eat a hat..my own.

I just searched and found pictures of the assembled BGE heads. The valves are definitely coated with at least a different color, but I will assume that the coatings too, are part of that "durability in a heavy duty environment" bit.

Thanks again to you both. School was painless today.
