SVO Cylinder heads for the 4.6L 2v NPI engine, How good do you think these are compared to steenracing.com stage 1 headswap package?

Those heads are by no means "new". They have been on the market for several years. They will flow better than ported pi heads write out of the box. When they came out there was a man from SVO that had them on his car to demistrate there potential. His 98 mustang ran 12's with those heads. They have been out for a long time, but there high price keeps people away from them.

SHM SVO heads: Intake flows 185 cfm @ .550 lift
Exhaust flow 148 cfm @ .550 lift
MPH heads: Intake flows 235 cfm @ .550 lift
Exhaust flows 202 cfm @ .550 lift

I think the MPH heads have bigger valves installed in them like the ones that come in the SVO heads. The SVO head is the best head for modular 2v as far as flow goes. Factory ported PI heads with factory valves are doing good to flow the same as the SVO heads.

Why is MPH heads massively outflowing them if they will outflow ported PI heads?
