A couple reasons why I hate doing port work after others

Nice thread apart from the strange ramblings in the middle?
I always port for myself and (maybe) sell the heads as 'done' (sometimes).

Most folks don't know diddly squat about the time and effort that goes into them!
So you are lucky to get any 'recompense' from wannabe drag racers at ALL.

A craftsman loves to craft and it don't matter if you is 29 or 69.
Flow-benches are a magical thing but a good porter knows what's right and wrong!

'Flow' high in the port is more important than low down.
Air like water, likes a straight line, any protrusions are a eddy point.

So I like to cut back the top of the port to within an ant's leg of break through.
Feel free to say ''I'm talking crap'', as most folks do...

Is this a small bulge or just a light shadow (blue arrow)?
ps How many heads do you need to port to call yourself a PROPER PORTER?:thumbsup:

Ya like I said these ports are not finished. I love these rotating stands but after the valve job and after they are off my rotating stands I stand the heads upright to straighten my side walls. That way I’m finish grinding the walls horizontally and not vertically. Every part of these ports are finished and measured at that time them Off to my flowbench. During the finishing process I use two sometime three different chairs to get the right height to visually see each port at different angles.
