Porting tee dee dum

[adrian101]

I want to port and polish my intake port and my exhaust port. so they match and i get a better flow of air entering and leaving my engine.

how do you do it, is there a rule to go by? how much can i shave off.

Any other pro's and con's of porting and polishing?

Any help will be very much appreciated.

Thanks for reading

Lots of info on this subject. Use the search function... This is the only mod I have not attempted, except the boost bottle. I've got a 66cc Grubee with the same billet head as you.
I might try it later this year... Just not sure about it myself.

Polishing affects a very small percentage of flow. Just make sure there are no "bumps" that would disrupt flow.
