I think the Blue Thunder high risers would be the top of the heap. Just my opinion. Like Jay said they are the best quality bare/machined castings available as well. They have more potential and have more average flow versus all out pro ports, if both are CNC maxed out. The high riser will have a higher entry angle and higher floor and roof both, by a large margin even versus the DOVE HR PIE ports, also better short side radius into the bowl then chamber.
Not to say that max effort CNC Pro Ports would be anything to sneeze at, and likely a very close second, big power potential and available castings. I think the BT heads have the edge also on the T&D rocker pad layout and design/strength.
Your results/opinions may vary.
I do happen to have a new/recent set (less than 24 months old LOL) of untouched BT HR quench chamber, narrow valve center (428HR) castings in the box. I waited 3 years for those to come available being on a waiting list. I also have a FE Power HR adapter and a 2 piece 1x4 Dominator race manifold that is superior to any 351C intake for a new top-end for my 487, swapping with my MR deal sometime within the next season. Should be interesting...
