They are gas vector rings from Jeff Lemons, along with new ARP studs which I relocated to be proper on center. The factory ones are not properly centered. Tim is making me a set of 321 Stage 2/3 custom headers to go with my very fancy 321 single Billet header flange that Jeff made me. All of it is machined to within 0.001" tolerance for perfect gas expulsion.

About 3000$ in work + parts.
The flow you are getting with the stock size valves is very nice. Which flow bench and at what pressure (28Hg)? Hard to tell from the pictures, but it appears that the port angle has changed.. Good work.

Something to look forward to . A customer of ours was running the same Vitesse Stage 2 turbo as you have, using the Vitesse Sledge-Hammer big valve head, Vitesse Cam and V-MAF+. The 951 was lots of fun.

See the

Good luck with your project.

Do you have a plan for heat management? Already a large oil cooler in the work?

I too find this a bit fanciful but head flow figures vary like dynos plus most don't recalibrate which makes the figures look even more impressive. No doubt there is good work on this head but no way it's seeing a true 270cfm with stock valves and cam no matter what alterations to the seats/angles. Not to say it won't be a great car but we can't really compare each others numbers from various flow benches.

The bench is calibrated with standarized orficeplates from SF

The intake has been redesigned ( smaaler inntake runner ) , i can post some pictures when i get it

The car is going in the Dyno in about 4-6 weeks ( dynapack / rotortest )
