Ok. Thanks for the info. I assumed he meant to say perfromer rpm because the regular performer is not up to the job for that many cubes. I just swapped from a T2 to rpm because I felt the low end respose wasn't there and I was gettin poor port velocity at idle with the aggressive port job on the heads. Since I don't race I am willing to give up a few tenths to get some streetabliity back. Ill be bolting it on this weekend. And yes, I too had to remove a lot of material to get the T2 gasket matched to felpro 1233s. The ports were still a little smaller than the head ports. Did not leave much room to seal !
