Got my set of Paul's cnc ported heads the other day and they look real nice. Short perform quite well also.

I'm wondering why they dont work on narrowing the guides? My edelbrocks from All Pontiac look a lot like yours do...

What size is the intake opening?

4.310 I believe. I believe Paul flowed them on a 4.150 bore also and there wasn't as much of a difference as one would think.

What is the cost of a new set of his heads that flow these numbers? I like the above-mentioned head.

Congratulations Paul - that is very impressive.
