Any Modification for 1mm Oversized Valves???

[philly90tsi]

Is there any Kind of Modification or Supporting mods you need to install/use 1mm oversized Super-flo Valves? Im not sure this is a newbie question due to I don't know many Newbies doing headwork. Thanks for your help!

Well you need to get the head worked so the 1mm oversize valves will fit and if you want to get the most out of them get the head ported, cams, cam gears.Just for the 1mm oversize You dont need to get anything but wont do much.

Listen to this guy, he knows what he's talkin about, I can personally vouch for that.

1mm over valves on a stock head with stock cams will pick up flow about 12 CFM.
