Summit has trick flow heads
are you referring to the head swap or the rocker arm swap?
I am planning on changing heads because my current eddy heads are 84cc and i have a stock bottom end 383 with the pistons way down in the hole. i am at about 8.5:1 compression. the trick flows have 78cc chambers and i will pick up about .75 points of compression. this will hopefully make my combo run a little better. they also flow allot better (as advertised) then my box stock eddy heads. they are also pre machined to accept 3/8 pushrods.
as for the rockers:
I currently have the comp cams pro magnum rockers with the stainless bodies. they are not the new ones with the bronze bushings. they will gall when i step up to stiffer spring rates and a solid roller cam.
