Input on some of my first porting please
Ive been studying Judge ITO's porting threads and learning from some local roto heads that have been doing this for 30 years.

I started today with one of my bad housings- Praticing on the exhaust ports. All I did was remove the material to the stock outline, and then add back the 2mm bevil that surrounds the port. Remember first time here and im working with nothing but a dremal and some carbide bits.
I know its not perfect, I also know that I lopsided the port edges, ones not quite stock shape. But eh' for a first try, its not that bad IMO.

did you check your ports with a plexi glass with rotor spinning on the plates? watch out your side seals and corner seals........

Ah why are you in grants pass BDC?

And I will check the sides seals and stuff with a plexi rotor, thankfully I have about... 10ft of plexi laying around.

Cant wait to get this motor together.

Very nice for a first port job!

Makes sure that you shape the top of your intake ports a bit more,especially the secondary ones.

Well done!
