so do you do head work? and i heard the seats be moving and will never seat tight as stock

i have seen several repaired with no issues, i suppose if its not done right there could be issues. lots of shops out there that are capable of your repairs. go ahead and have oversized bronze seats in if that would make you feel more comfortable with the seat issue

Yes we do..the only reason that the seat would move around after the repair is because they were installed too loose(not enough interference on the fit)...some can install them correct and some can't..

well all different metals have different characteristics such as absorbing heat and malleability. bronze is a softer metal than steel so it would in theory increase valve life and absorbs heat faster then steel and again better for the valve, can be very beneficial in a turbo or nitrous engine. bronze, like brass, is a copper alloy, and if im remembering correctly that bronze has a high tin content making it stronger, less malleable, than brass....ape's site kinda backs me up on this APE - Oversize Bronze Valve Seats and claim they wont move in the head as much as steel

i am not setup to tackle this myself, contact one of the site sponsor and i am sure there is a part and labor cost on this. you have to understand that the tools alone to do this type of job are expensive. usually they will make you a package type deal like for porting, oversized valves and seats, springs, and so on...and with some good cams you are gona like the outcome
