Cnc 243 They were a set of CNC 243 heads.Dont know much else about them.Part of the motor kit this belonged to.I had a chance to help dyno one of these a couple months ago.It made 592 HP.The whole motor is from WEGNER Racing Engines and its a piece of art.

Clutch& cam Quartermaster clutch kit.And I think its a off the shelf Comp Cam.a 281 roller.It can spin to 8000 rpm on upshifts on restarts but can run all day at 7000 rpm.They told me power is in the head flow and they are not saying anything about that,I tried.

Ls2 Spec Motor You can only run what they send you in the kit,or you can lease a built motor.Everything has a coded square on every piece.The most you can do is tune on the carb and timing.Its for an even playing field.
I think the conversation of dual vs. single all depends on your valvetrain dynamics. Why, if your valvetrain is 100% in control, no valve bunce, would you even consider dual springs?
I think the reason a lot of shops use the dual valve spring setup is because that is what they have used since they started building engines. It has been proven over and over that if you can keep your valvetrain light, you only need to control it with a beehive valve spring.
And, vs. a standard dual spring setup, a beehive will out live a dual and be less harsh on the rest of the valvetrain components.

Guys, please keep this thread on topic. Enough of the valvespring arguments. Just take the photos for what they are. I, for one, am happy this gentlemen snapped pics and came here to share them.
I graduated from there August 2003.
Wegner ports the heads. They get the hp at high rpms with a carb intake and a GA like cam which is not terribly streetable.(why should it be) Light single springs (PSI) and valves.
