I was looking at the gmpp heads.
The afrs I was looking at was a whole extra grand.
Are the race rites you have worked over?
Otherwise what's the advantage of just buying them from summit or jegs versus Mike?
Also I would be interested to hear the quick specs of your whole build, cam specs/ compression, etc. As mine isn't quite done yet.
No extra work except smoothing them out in the intake ports theres a lip after the CNC in the opening. I went with CNC chambers.
He can order then with valve seals on the exhaust from summit or jegs they only have on the intake. When I bought my heads(actually have bought two sets) he was cheaper and have better customer service.
Its a 10.4:1 489 built 2007.
