I was going to build a second race motor in case I had a major break down? It was ported the exact same way as the one on my car. I don't have any flow numbers, but my car is a beast with it.
Here is the break down.
782 Swirl Head
Mild intake/wild exhaust
+1mm valves
Heavy duty springs
New retainers
hardened MP locks
Should be a very stout head that will produce some great numbers...i
Asking $900 + shipping (feel free to make an offer too)
