I know we are working on cams and shooting for 25-50 HP gains, but this is a reminder that we got 60 HP on a 16.5 PSI turbo kit with only a headwork and re tune.
And 500 RPM quicker spool.
Easy way to squeeze more power out at same PSI and picking up response.
We can turn these around in about 4 weeks.
Details, Flow Charts here. http://www.urgedesigns.com/velocity.html

- We include the following
- CNC porting to ensure symmetry between ports
- CNC Valve Job
- Hand Finishing for extra 10-20 CFM gains
- New Valves to match seats, Inconel EX valves for turbo/superchargers
- New Valve Guides
- Install your Supertech Dual Valve Spring kit or our optional Dual Valve Spring kit $600

Interesting stuff. I am in the market for getting my F20C head redone. I have not decided what Ill do, but at the very least I need guides and valves. Are the prices listed on the site page posted include valves? It does not clearly state what is included.

If you want to go to 88/89mm chambers we can make seats larger for a bit more flow with out decreasing air velocity. In that case you will need at least new intake valves.

Same boat im in! If I have any money left when my shortblock is built I will be doing a built head! I am pretty dead set on having 4Piston do my head but if I can see some hard evidance and a better price I would totally go with the Urge/Eyden setup!

Our Turbo HeadFlow..
http://urgedesigns.com/boost-velocit...ck-graph1.html
4piston..
http://www.4piston.com/heads/ProS2K.html
Both using Superflow at 28" of H2O vacuum
At .300" We are 13/70 CFM ahead IN/EX (gets flow going at lower cam ramp)
At .500" We are Even/70 CFM ahead
4piston is a Pro Head with 37mm IN valve and large ports.
URGE/Endyn is 36mm IN Valve and Small port for Turbo. Since we have smaller ports/valves our air velocity is higher for better torque & response.
We have bigger port and larger valve designs for our Racing NA engines and have another 10-20 CFM on the intake which matches K Series Drag engines..
Our better exhaust port improves spool significantly, improved 500 RPM with 60 HP gains on 16.5 PSI
We are $2000 with New Valves, Inconel Exhaust & Guides.

You sir just made me change my mind when I choose a head package! Keep up the great work! I wish more comapnies out there for the s2k market put in the R&D that you guys are doing!
