I am having the good fortune and pleasure of porting for a good friend and drag race pal a iron RAIV head to match one that has been ported already that he came into possession of.

The head that has been ported is an original production one ( the other over the counter) and has been said to have been ported by our great recently departed Pontiac guru Pete McCarthy.

This ported head was set up for a 2.15” 30 degree seat valve and flows very well for its 1.77” to 1.80” throat that was used seeing that these heads can go 1.850” safely as compared to trying that throat size in a iron D port head.

Here are the stock flow numbers and the as received ported flow numbers @28”

I have not CCed an intake port yet, but will do so and post that up before the end of the weekend.

.100”——-84.2——54.2

.200”——-148.1——-148

.300”——-193——209.3

.400”——-213.7——247.4

.450”———————258.2

.500”——-223.7——272.9

.550”———————282.7

.600”——-232——286.2

I will post up some photos and port dimensions later today.
