Teaser Polishing intake is not what I said not what you want to go for you actually want a rougher finish on the porting because the small grooves create turbulence and that's what helps to atomize the fuel
It's a bigger thing for a carb engine but has little effect on injected vehicles
A carburetor has to mix fuel and air by time it gets through intake to combustion chamber
An injector sprays a mist
Hence the air and gas has been atomized by time it sprays out into chamber

I just went off their theory
And cleaned up the casting marks and if you look closely at how the intake ports air flows stock
The goal is to clean up any intrusions and I wanted to get rid of the kind of lip and bend inside the port which seems to restrict flow  once valve opens
I also might back cut my valves at 30 degrees
I'll try to draw a diagram of the material removal

As for combustion chamber
Polishing I believe smoother surface helps with heat transfer and does prevent carbon build up but the main thing Is keeping consistent lower temperatures promoting cleaner burn
Higher power

I wish I could illustrate better
But it basically was bottle necked bad inside I just cleaned up the casting marks and made a cleaner less restrictive path to the valve opening

Sent from my iPhone using DO THE TONhould be noted port and polish is a theory
That some believe some don't
There is a wrong way to do it and a right way is how far you wanna go with it until it becomes wrong

I believe in more air more power
I've also known all the highest power producing engines all have this service done
So it's something to be said why it's done if there is no real gains ???
Because it can improve your engine if done properly

Yes I know what you mean
I went for better flow without changing or slowing the velocity which would be a result of opening up the port diameter

I kept port openings stock size minus roughing with 80grit also the left was 3  thousand diff than right stock cast I'm  going to counter sink the inner diameter too and clean pass on the face
These 360 heads need just clean up of casting and the amount of material and where removed should be what I wanted
We will see one day how it affected my motor
