These Heads TBI
Fast355 thx for helping me with the VORTEC information but still not sure I want to go the vortec route. I have a set of highpo chevy heads. Wille they work with the TBI system off of my L03? Here is the information. Once again I am trying to stay within the the smog laws but I may just have to VORTEC or start with a TPI car?

12480034 - Phase 2 Cast Iron Bow Tie Head.
The Phase 2 Bow Tie cylinder head (casting P/N 12480034) has the highest performance potential of any cast iron Chevrolet head. It is intended for off-highway applications only. Although the Phase 2 cast iron Bow Tie cylinder head has the same casting number (12480034) as the Phase 1 head it replaced, there are several significant differences between these two heavy-duty cylinder heads. The Phase 2 cast iron Bow Tie head can be identified by its redesigned outer water jacket wall with a machined bar between the exhaust manifold flanges. (Phase 1 castings have a raised parting line between the exhaust manifold flanges.) The area around the tapped water temperature sensor hole is also machined flat on the Phase 2 head.

It will work with a vortec carb intake from your preffered manufacturer and a carb to TBI adaptor.
Keep in mind that this is basically like modding an LG4, everything pretty much has to go. Exhaust, cam (if your keeping the engine), intake, probably the rear gears and non-posi carrier, trans will likely need some mods to make it stand up, or be replaced with something stronger (MAJOR PITA), etc.

If I took these heads and with performer intake with a TB adapter plate would it work out as well as a Vortec engine?
Was recently traded a 383 (was a l98 engine to start) with bad heads for an old four-wheeler I had. Is this worth putting together instead of finding a vortec 350? Once again I am at a point where I can start doing the engine build now with just a basic rebuild of an engine I already have or will I need to track down a vortec for the camaro and save the 383 for the Nova? The only reason I am hesitant is I am completely new to any of the hotrodding done with computers. I am learning.
Thx

Dimented,
I juts returned from a deployment and went outside and checked these heads and they are definately not vortec heads. They are perimeter bolt hole and at least 10 years old. I am still thinking of buidling around these but just not sure about the EGR/Emissions.
1. Is there way of looking and figuring out what year these were manufactued? Pre-87? Only thng that concerns me really since I want to do this as cheaply as possible.
Thanks Again
