There are several choices out there today. Many of course where not covered by the article in GMHT. Check out this article about a head cam package we did for GMHT http://www.gmhightechperformance.com...z28/index.html.

We can do these heads, cam, and pushrods for $1450.00 plus shipping. Keep in mind this our "budget" CNC ported 243's that flow around 300. Our stage III heads on a 3.905" bore are going to flow around 312 and 320 on a 4.030" bore. These will also have excellent .200"-.500" flow numbers. Keep in mind when you are looking at flow numbers to pay attention the bore size used during testing.

If we can help in any way with your combination, please let us know.
