are there any motorsport A460 heads left out there? if so what are the difference between them and the tfs a460 heads that are found everywhere other then the cc chambers being smaller? do they flow better?

The exhaust flange is slightly different; they don't flow any better.

The tfs heads are far better imo than the older Motorsport. The old heads are not as good quality aluminum and have porosity issues.they take lots of work to flow what the newer tfs heads do out of the box.

i picked up a set of bare tfs heads. thanks for the replys, i was more concern on the compression ratio being so big and didnt want to run a dome piston. that was all.

Noting wrong with a properly designed dome.
