Porting TFS A heads and intake

Post  dirt_worker on November 22nd 2012, 12:41 pm

I have an a newstyle tfs cast single intake and lightly cleaned up 2.35 tfs A heads.
Would it benifit any by porting on the heads and or intake if everything else in my combination remained the same?

Heres my build...

my engine guys flow bench is known to be conservative and these heads flowed 400 and 300 on a 4.400 bore (we used that sleeve since it was the closest he had to my engines bore size)

My one set is going 465 @ .800 with a 45 deg valve job and a 2.35 ss valve they can get over 500 with alot of work and a serious race valve job and larger valve.
