I always run a stock 1.60 valve size on speedmaster or Edelbrock heads. I can hit the port speed number I’m looking for. He is going with the 1.60 Liberty Pro series valve on the exhaust.
ahh ok, i wasn't sure what those came with, i think tf's are 1.58...
I do have a quick question though.. is there a point where more cfm is useless.. Like me, if i'm honest how i drive i usually stay under 6k and not going to the track, is there a point where say 250cfm is as good as 300 if you don't go over X rpm? or perhaps even better under 6k with less cfm and more velocity? or.. too many variables. Just some thoughts i had earlier, not thinking of changing anything right now
