so alan said to me head had only very mild porting on inlet side and a polish. i would like to be having 32 psi straight in but im not gonna take the head off until something fails. unless its my inlet causing the surge, someone has said on here theyve had a 4x4 plenum cause surge on a t34 at 32 psi so i may try changing the inlet ?
