EQ head build + home porting advice sought

I have seen a bit about LXguys setup and was very impressed and inspired. Right now I have a 8 3/4 with 2.76 but looking for 3.55 or 3.73 depending on what I get my hands on. 727 with 2500 stall already in the car will stay. Probably a 28inch tire? Just guessing I'm not well versed in tire diameters(will be running 15x7 or 8 police wheels eventually).
Did your EQ heads have the big ridge around the exhaust seat?
