Intro to a port job
You can lay another stone down, at the same time some angles and size... help flow in the wrong direction.
Theres a cutter that brings 5 angles and puts nice shallow bowl around the intake where the chamber shrouds and up into the plug boss a hair .050 wide angles 75,60,45,30, radius top.
Its said the ledge on the exhaust 'chamber side'..to leave the lil ledge near the chamber. I'd say its dependent on what's done up to that point and where the seat is but mostly accurate.
As I said in some other thread...on the intake.. The top cut, lip, that makes some guys drool is not the end all. Remove the lip and put the seat down more and down you have more influence with the valve job. That's not the end all either, but it does change the curve a lot. I like a deep 60. Ram does good on that as far as I can see. I'm waiting on my stone to do 60, atm only on the exhaust.
When you start doing it yourself..you begin to see how little effort the head guy st the local shop puts into your valve job. It does not take long to lay a couple more angles if you have the pilots and holders to jump around.

Yes. Looks like a basic 3 angle vj to me too.
