How much is this stuff worth. (top end of engine)
Here is what I have.
Vortec L31 906 heads
ported
screw in studs
guideplates
radius valve job (just like the winston cup valve job)
Comp Cams valve springs set up to match XE268 cam
valve guides machined for higher lift cams
Vortec style Performer RPM Air Gap intake
Comp cams XE268
.477 .480 lift
Comp Cams lifters that match the cam.
Cranes Blazer series hardened pushrods
Proform 1.6 roller rockers which makes the lift .508 .512
I am needing to know what I should ask for all this stuff so that I can proceed with my 406. I am running out of dough. If I can't get what anything out of it I'll just keep the stuff. If I take it all apart I'll number all the lifters, pushrods and rockers. The stuff has about 1500 miles on it at the most. This could make a 12 sec. combo easily from a 350. Would I be better to part it all out?

Come on guys. Someone must know. I also will have chrome centerbolt valve covers to go with the heads. Complete 12 sec. package should be worth something. Right?

Heads: Look at the price of new Vortecs, find out what the machining and parts you've put in would run, add it all up and divide by half.
Intake: About 75% of cost of new.
Cam: Include the lifters and pushrods, ask 1/2 cost of new cam.
Rockers: Offer to pay someone to take them. That you didn't break any in 1500 miles is a minor miracle.
