LS1blazer keep in mind cncing the chamber will make it larger to begin with. It really depends on where the chamber is before milling. Congrats to the guys that dropped nearly 3 tenths & almost 4mph on a mid 10 second car by swapping the GM head for the PRC l92 head. I think that speaks for itself way more than guys with no cylinder head experience liking a head based of pics.
I'll keep working on heads that perform on the dyno & the track while other people keep deciding what they like based off online pics..
Who else can claim 4mph gains over a stock l92 head by just swapping to our ports? Nobody but the New PRC L92 port.

Greg Good down in Houston at Greg Good Cylinder Heads ported mine. Very happy with the results. Too bad they flow more than a 408ci engine needs and dont have much velocity on a 4.030 bore due to the intake port size. He did not touch the intake ports much, it is just the nature of the head to be a lazy port. He also cut the intake valves to reduce shrouding.
How many head porters are using a smaller intake valve?
