How does my exhaust porting job look?
Followed the RB template for the street port. Replaced the bevel (chamfer) best that I could. How does it look?
I didn't change the sides to much but opened it up on the bottom to match the exhaust sleeve. I also polished the exhaust sleeve.
Thoughts?
Already had one comment that says I need to increase the amount of chamfer ....
This is my first time...so just want to make sure i didn't F up new housings.

Just FYI
The F1 engine teams would now mount the 'head' and the exhaust header/manifold on a machine that passes a high grit plastic paste backwards and forwards through the port and pipework to ensure a perfect/seemless fit.
If you've got a few $10Ks around..................

Mate, it needs to go bigger everywhere, up/down to the sides, when you look at it from out side you should see not rotor housing edges just sleeve.
I'll take some pics of ones I just complete for a customer.

i'm building a large streetported fd, equipped with a hks t51r turbo
plan on running 25 psi. These are my exhuast ports.
The one on the right is a large exhaust port by Rmagic Japanese tuner that I took out of a car I rebuilt last year, which had to4r turbo and mild street port. The one on the left is mine for a comparison.

If you can find a putty that will take 1800F
Not sure JB weld can live up to that. And worst case is that it comes out and hurts your turbine wheel

Makes it tough to pass emissions testing if you weld them shut.

I might be porting mine tommorow, the shop that did it last year barely touched the exhaust ports. It looks like they just glazed over them with a dremal. Not impressed at all.
Is a dremal good enough to do the job right?

You want the air to flow in only *one* direction, there is no gain to allowing air flow backwards! The "step" does not hamper forward flow to any significant degree while it puts the hurt on reverse flow.

To late for me...I used the RB templates...
About 30 miles into my breakin period...
I will keep my thread updated on the power it makes...
