Stupid thought big block chevy type head.
Sorry this is something that popped into my head. and nowadays there would be a very small market for them given the cylinder heads available and what most people are looking to get out of them.
Basically the small block mopar was first a hemi engine, then turned into the poly engine. That's a well known fact and why sbm have that funky lifter angle.
So given that lifter angle you would think it would be easy to make a more modern performance oriented design to the old poly head. And yes of course you would need special intakes and exhaust but you need these if you're running W2's
