I port and polish Iron LT-1 heads based on Joe Mondellos recommendations.
My Heads made our PINKS ImpalaSS run 8 tenths quicker.
Smooth sharp edges, can reconfigure to make chamber smoother
Open up back side of Intake Chamber. Polish with flapper paper..
Will increase 1 or 2 cc but can be recovered with a little milling of the head.
Benefit with polishing, will help prevent pre-ignition, better breathing will help HP.
