I ordered a street port template from RB and used it to check the previous owners porting workmanship.
The red line is where the template shows the boundaries of the port should be.

Does it look like the port is beyond fixing?

Sorry forgot the pic.

 

Here is the pic........... ash

 

It looks like its just a bigger port job. I dont see anything that jumps out at me that says there are any problems.

Not sure how the stock ecu would feel about it.....

I would use the same theory you used to check against the rb template to check that all the ports are the same.
