Jesse did this motor ever end up in the car? If so how did it run?

Also you said "Good info on the differences between the RHS and the EQ. The RHS is wider at the pushrod crossection of the intake port pair. That means the intake port window at the pushrod pinch can be larger on the RHS. I was trying to get RHS to cast a version of this head with machined pushrod holes which would open up the option of machining them wider for use with offset intake rockers. But it's like Ross Perot said of GM, "It is easier to get an elephant to tap dance than get a big company to make a change." "

Could I just have an even bigger hole machined into these and then sleeve them to get a little more pinch cross section?
