John, I got the heads from Brian. They were ported by Jason Short in NY. they were completely broken down by my machine shop. They flowed right around 255cfm at .500 lift. Chambers are 54cc's, valve springs are comp 977's with Ti retainers and locks ARP studs and Comp 4084 guide plates. Before they were put back together the valves were lapped and seats cleaned up. I don't know what the installed height of the springs are off hand. I belive they were set up at 1.800 so they should be good for .600 lift. I'm using Mr. Gasket .026" gaskets. The intake was also ported by Jason Short. Nothing real fancy just a basic port job on the runners and the TB was opened up to 58MM. Finally the cam is a Comp Cams "306" LT1 Camshaft, 230 / 244, .510 / .540 112 LSA

I don't know of any Engine Builders in the area unfortunately. The good thing is I have two spun LT1's so I can get my original rebuilt and leave the car alone until one is finished. What kind of money am I looking at for a basic 355 fully assembled, and a time frame?
