My dyno guy Don West buys a lot of SB2 heads from the circle track shops...used of course. He also plays with the out of date pro stock heads a bunch. Any head that is for a race application is expensive. The parts involved to support those heads are going to need to be top shelf.
Titanium valves are about $100.00 each for the custom sizes. With a port as high as the DR or CT your in the 6.300 to 6.400 length. Guys would give their right arms to have ports that high!
You pay for what you get, my Jesel valve train has been very good to me at 9000+ RPM. I just got my set for my DR heads on Friday.
If your paying $150.00 for flanges your paying too much. A local fab shop here cuts mine on a laser table 4 at a time. I can get you a price. I should have a price for stainless shortly.
The guy in the video was Thom Bates. He is not an engineer but he works (or used to) work with the engineers on many of the GM Performance Parts products.
Due to budget cuts Thom was let go just after SEMA.
I enjoyed working with Thom while he was at GMPP. He was passionate about the business.

Hahaha, hey Phil who pissed in your Wheaties?? When did the costs involved in a trick set of heads ever sway your spending?

No one pissed in my wheaties. My comments were directed at the guy doing the interview that said "Plenty of people run jesel rockers on the street and the cost of custom valves had no bearing on if people ran them BUT the need of a custom flange was the deal breaker." The heads look very promising. My beef was not with the guy from GM but the interviewer.Hahaha, hey Phil who pissed in your Wheaties??

After spending close to 10 grand for that set up why would a set of flanges "break" the deal. Sorry it was 6 am when I read that.
Still Thom is a good guy and probably had a little slip when taping that deal.
But now I can poke fun at Tom! LOL.
My apoligy to Phil.... good point!
Have a good day!
