if you haven't done it before then i wouldn't suggest making it your first project
the way I have seen it done is to mark the outline of the bore needed on the part being ported by using a gasket or making a paper gasket
I can def back up maxbore.com as I have known the owner and his work for many years

I see people out there spending money on the car to improve it … If you spend half that effort just working on your driving skills, making you and the car work together as a team, then you’ll go faster – period. To make the car go a second faster on the track takes a lot more energy and money than making yourself drive it one second faster.

Just use the gasket and trace it with a marker. Grind it away untill you hit the line you made or all the marker is gone.

to port match the intake manifold to the throttle body install the throttle body each screw twist twice (it will stay loose) open the throttle body and mark the whole circle of the throttle body with a permanent marker and there u go u can start grinding

+1 thats how i would do it. not all gaskets are the same. 70mm for all motor would give top end power at the sacrifice of low end. so pick what you want and go from there. IMO its over kill unless youve got huge cams, large ports, and a big bore to move all the air.
