This is my PS...I forgot to add it....Also whats bits to fit in a 1/4 inch air die grinder to port with.......

 

Yeah sry about that guys...Redhead here....lol....I bought a die grinder...not a dremel..My mind was elsewhere. Bren

 

Using a 1/4 electric die grinder with double cut carbide bits is the best way to remove the bulk of the material. Going back over the area with a single cut bit will help make the surface a little smoother. It might also be wise to pick up a template from someone.

I usually use a "christmas tree" shaped bit. i.e.:

A little WD40 helps, I've noticed the burr is less likly to grab and jump. (not cool when you are working with critical sealing surfaces)

 

OMG guys thank you so so so much!!! You're awesome!!! That so helps and I can get started now...As soon as I have that done I can put my engine back together....YAY!!! Thank you thank you thank you!!!
