Small Block Aftermarket Heads

The only iron Ritter block I've EVER heard of that is running just went 5.74 @ 120.01 last night at Irwindale on a small tire leaf spring car..... and that was with a 1.28 60 time so 9.5's might not be out of the question. QMP did the machine work and it was a monumental task to get the block in usable condition. There is a guy from Kansas that's currently doing a build with the aluminum block and has had a couple of pitfalls, but most were pointed out my the owner of the iron block that is alive. He had been updating the build on Moparts.
