Thanks I'll check it out

I just looked again at CL nationwide......there are Vortecs for 150.....

BEWARE Real "Vortec" heads are easily identified....they have only four intake mounting bolts per head. They have center bolt valve covers ONLY. Vortec heads were put on 96-2001 GM 350 engines installed in trucks and vans. Vortec heads are the best flowing stock GM heads that will fit a small block. The intake gaskets are unique to Vortecs.

A vortec head will require a vortec intake manifold such as an Edelbrock 2106.....inexpensive manifold. The heads also require the proper guided rocker arm.

well that sound s good but getting out of a machine shop for a $100 with done heads would have to be very nice heads to start with and you still would not get out of my shop brake down tanking them and mag job + a valve job puts you past $200 thats EZ to do.you have to ask your self what your not getting for that $200 set of done heads on craig list? . i have head casting for 350 chevys that are good cores not hard to find its the labor to do them right that cost
