I have a set of rectangular port aluminum heads. They are about to drive me crazy with issues.

1. I had to have the water jacket ceramic coated because the were seepin water into the intake ports.
2. I had to put helicoils in a couple of intake bolt holes and a couple of exhaust port holes.
3. Now the bolt on the rigt side middle port is stripped.

I met Herb McCandless last year and he told me that rectangular port W2's were made by Diamond not Batten. Stamped on the head is RAM with a date. I was told that RAM stood for Richardson Auto Machine back east.

I am ready to pull the heads and put heli coils in every bolt hole including the rocker stands. It just seems that the aluminum from the eighties is not anywhere close to what is availabvle today.

Any info/opnions would be appreciated.
