Thanks for the heads -up.I must have been looking at the wrong part # on the web site.The page I was looking at referred to a set of heads then gave a price.I have since found a price for each head at jegs for $365 ea..So the $380 from summit was for 1 head.They look good but I don't want to spend that much.It's not that I won't have the money ,It's a matter of spending to much on the overall project.I don't want to sacrifice quality either.It looks like used GM products are the way to go.
