Head Porting basics

Thank Justin, I haven't skinny up the guide boss to release the head bolt bump(as u have suggested) in the roof and want to do that first to see where the air changes with my fps probe.

I'm glad you thing i need to straighten that wall, as i think it need to go too (Had read somewhere that removing that bump in wall would kill flow)

I want to make sure i understand this,......once you have remove to much metal......well you have remove to much metal!
I should leave most of that 75*cut on the ssr alone?
I was going to radius it back from the seat area.........or does this affect the hole venturi idea?

Edit: Not layed back just rounded up to the seat.......NO???


Thanks again!!!

Yes rounded/rolled.

I see the idea behind leaving the head bolt bump, if you you're looking at the port like it's a crooked sb chevy, but in this case the la port is fairly straight and if you open the pushrod pinch up you don't need to try and get the air to turn to the right or left cause you can get a good straight shot to the bowl.
