What sucked was the replacements were no better than the ones I had replaced.

yes. A few years ago a friend won a raffle and the prize was a set of brand new rhs320 heads. They came direct from comp cams. I bought them from him, bare, and teh valve jobs were so bad on both heads i decided to contact rhs to see about getting them replaced. It took being persistent but they finally agreed. They were out of stock at the time so they had a pair sent to me direct from the machine shop which was royal oak boring in oxford mi. I still have the shipping receipt. It says under part name "bbc pro action china head".

What did you and your head guy think of the rectangle shaped exhaust ports?
Our heads are going to the machine shop to check/adjust the exhaust guide clearance a little. I must say, I was impressed with the port design of the EQ heads. I was a little thrown off by the rectangle exhaust port shape as I just expected it to be a D shape but overall they looked like a very good as/cast design to me.

Those are good numbers. Back cut on the intake makes a huge difference in low lift numbers. I have a new set of EQ 320's here that I'm doing a valve job and blower marine prep. Staying with the 2.25 valve and not doing any porting. I may throw them on the flow bench just to see how they compare.
For Mild Thunder's comparison:

Any advantage to that shape vs a D shape?
