Thanks, and yes the early 86's and all 85's had cast iron heads. I have heard that they dont have a lot of meet to grind on but I need to investigate this further. I am a machinist by trade and could get myself onto a milling machine if necessary.I already have a die grinder with some carbide cutters as well as a Dremmel tool.

I could have the valves opened up I think to 2.0's and 1.6's. I mean the Fastburn GM heads and the AFR's flow 190CC's. I would think this is possible and I will investigate this further.

I just orderded the John Lingenfelter motor building TPI book book and the book How to Tune & Modify Chevrolet. I hope they will give mesome flow numbers so I can determine how much meat would need to be removed. Noone has said it cant be done just that its expensive to do on iron heads. Hey time is all I have a lot of !

I like the roller cam idea alot BTWQ.

Thanks again for your input.
