I will be buying new heads sometime in the near future and i am unseure of what i wanna go with. i know it will be an AFR head but i dont know between the 165's and the 185's. My combo is a balanced 306 w/JE/srp flat tops,trick flow street heat (eventually will go to track heat/systemax) 1.6 rr's,24'lbers, 76mm C&L, 1 3/4 longtubes, and im gonna go with a steeda #19 for emissions reasons. Last season this combo with a comp xe 274 cam, ebrock performers w.56 cc chambers (angle milled) cleaned up ports and worn out valve guides put out 285 rwhp w/4-500 miles on the shortblock.I want to make over 300rwhp this year which i had thought would have happened last year but i want to do it emissions legal this year. Also next year i will be adding an S-trim or P1sc and will run around 10-12 lbs. Which head to go with? the 165's or 185's? I know i will loose a lot of lower end with the 2.02 valve's on the 185's but will they be better for my future blower combo? Thanks to everyne in advance.
