I am doing some porting work on my VCT head and need to know how much material can be taken out of the exhaust port. If I look down the port I can see a flat section on the floor where is enters the bowl, the port does not line up with the bowl and turns a sharp corner, can I remove a bit out of here?

leave the flat floor there. you'll hurt the port by rounding it out

Like what he said ^^^^^^, don't touch the floors, can be smoothed, but take none off.

Not the floor but the sharp(ish) turn the port takes to line up with the bowl.

Do you mean a casting line/ridge??? Where the sections of the mould join together.

No, the 3 o'clock part of the port where it enters the bowl and adjacent the guide is where I am talking about.

After an extended search I have found the USB cable.
Here is the area I am taking about circled in red.

Are all the ports like that or just the one?
Use a inside calibre to measure the circumference of the throat entry into the bowl. which ever is the largest you use that as your target for the rest.

personally I'll just give it a clean without going to far. you don't want to hinder gas velocity to much.

Thanks Slick good point, they are all like that. It was not so much the guide to wall volume that concerned me but the sharp bend. I am probably not going to do anything there now as I am nervous about the water gallery.

Next question, is this area a hangover from the swirl ridge on an EA or is it purposefull on an AU?

This pic is of an EF head, a 94 AB. The pics are before and after polishing, as you can see, there was no little ridge. I haven't done many AU head gaskets, so I haven't seen this before.

There ya go.....I have never done one of those. I have had to replace the VCT units on the front of the heads, because they had porous castings and leaked oil.
