383/489 Stroker

almost no mopar head will compare with a bbc ...
and yet some don't get that.
The WORST bb chevy head, the peanut port head that every chevy racer throws away, flows better than a stock 906/452 head..
And a decent aftermarket oval/roval port head outflows a cnc'ed 270 TFS head. And so does a $400 ($800/pr) speedmaster head.
