89 TBI heads?
Bought a 67 camino with a "fresh" 350 in it. FOund out today that it has 2 different 305 heads.... so i yanked them... My neighbor has a complete 89 350 in his garage. he says i can have those heads in trade for some tranny work... My question is. How are these TBI heads? i have read a few posts that said these were garbage.... i look at their signatures and they are running near race motors....
This will be a daily driver with a .465/.465 cam .... I don't need race car statsu but i don't need a slow piece of crap ! Just looking for opinions. Also thinking of going to the junkyard and looking for some vortecs maybe? Or just some decent 350 heads? I dunno... Anyone in Orange county Ca that wants to trade a demon625 carb, ps3 or some cash for some working heads? Register now (free) or login to remove ads

TBI heads are swirl vane heads. Pop the valve spring and remove the intake valve, look in the bowl and you`ll see what I mean. These heads are great for a daily driver low end torque mileage getter. But since the swirl vane restricts flow so much they are out of breath at 4000 RPM, making them useless for a performance engine.
