Throttle Body Porting

[hawaii-5-lo]

aloha everyone,
im taking off the throttle body to polish like glass.i think i will do the bump-stop mod,grind of the back of the butterfly screws,i want to port it also,i will also fill the PCV hole with j.b.weld,what size hole do i drill through the epoxy?,anything special about taking off the TAC motor?sorry so many questions,i like to plan my attack before hand.this will go good with my ported MAS,halltech T-1 with shroud modded,lower t-stat and fans,gutted cats.does NAPA carry the 'o'-rings for throttle body?thanks for any input,Todd.

Becareful not to go to large or you can really mess with the idle. I have thrown a few away because of over porting. The TB gasket is on the manifold itself and after about 500 installs I have never had to replace one.

Goodluck
Brian
