W-2 heads, whats the going rate?

My first reaction is that it sounds like a pretty good deal. I think you want to get a part/casting # for them and see which ones they are and when they were mnfr'd. There were/are several different W2 setups (Econos, Basics, Race, etc.) some of them having traditional rocker arm stands and some without meaning that special blocks, shafts, etc, must be used. They also came with several different sized chambers and that might be a factor as well. Re: the adj. rocker arms. Just make sure that it is a W2 specific setup. Remember, W2s have offset intake rockers and rocker arm assemblies are not cheap. Good luck and let us know what happens.
