I'd like to see a head that looks like the 440Source (meaning stock-appearing) but flows like a TF270, but I'm probably in a minority.
That would be cool for sure.
Having a better combustion chamber would be the icing on the cake!
I've had CNC ported Stealths on my '63 for over 9 years now. They flow about what a TF-240 flows. No issues and I've beat the crap out of them!
