Cylinder head porting - Toyota Corolla Levin, 1.6 liter, 1994

Started porting in June.
I still do it, because little free time ...
Readiness 50%

At the moment, I have almost finished cutting the exhaust channels ... I wanted to increase the diameter of the channel at the outlet to 36mm, it would take three days of continuous work manually for each channel))))
I took my head to the turner, traveled all over the city, only one agreed to take it (it would be better not to take ), I will not arrange advertising for him)))

He explained to him how to drill a channel, depth, diameter, and so on, he threw everything at him, offered to help him (as he felt), he said to come the next day, he will look and say whether he will do it or not. I come the next day to him at lunchtime, he’s ready to take it, only I did it by 32mm (stock size) ... He says the wall will be thin, he will open the channels ... And he broke the price of 2k. rub., I paid nothing to do ... I went to the garage, began to measure all the channels, the result: 3 channels - 32, one - 33 (and the center left) all planted at different depths ...
I went back to him, began to show him to explain - I will tell you and he did it so cheaply (expand four holes with a drill), we started kusanina with him, it almost came to a fight)))) But 1k., I returned it from him, let the second be on his conscience)))

Now, because of such a bad person, I have to redo everything (clean up all his jambs), next time, if he is (most likely in a year), I will buy rough cutters and quickly remove everything with them)))

The cost of cutters amounted to 1500 rubles.
I'll post all the pics when I'm done...
