Ported 1.6 Head
I've got a ported and polished 1.6 head up for sale. I have the valvetrain parts minus intake cam and it's unassembled right now so you're pretty much paying for the port work but I can send the head off for a valvejob and assembly if the buyer pays for the work. Asking 250+ shipping or can do $200 shipped if buyer sends a core in return

That head needs a lot of work with paper scrolls before it is considered finished. You should have taped the mounting surfaces before porting. The mounting surfaces will have to be resurfaced in a big way.
It also looks like you removed alot of material from the floor of the port. Did you?

From what I've read taking material from the floor is a bad thing. It'll lower the intake speeds.
What experience do you have porting heads? I know you sold that built engine a bit ago, did you port that head with before and after results either flow benched or dyno'd?
How much for the valve job at your shop? Could that be done for 1mm+ over sized int/exh with the valves properly backcut, bowled, and no leaks? Could they also look at the head and see if it's even useable? How much extra would they charge to smooth and polish it up?

Well if you get it checked out anytime soon lemme know. Right now that tidbit didn't help much. If he didn't get it running and you have yet to try it out. We're still at square one scratching our heads.

Only experience I have is this head and my first one so I'm no pro and can go back over it to finish smoothing everything over and polish up the exhaust side. As far as the bottom hurting flow I'm not sure and didn't get before and after numbers on the first head either. The machine shop has a CNC machine and a flowbench to check everything out. Thinking back from memory when I sent my first head in it was around $340 I believe for the machine work for larger valves, valve job, new valve seals, and to get everything checked and installed. Sorry if I missed any questions just ask them again.

You never remove large amounts of material from the floor of the port, just enough to remove the casting flash. All material should be removed from the sides and top. That is why a 99 head is so much better than a 94-97 head. The runner has been raised to straighten the path of the intake charge.

I bought the bottom end, it's installed and have been happily boosting 13 psi the **** out of it, there is no quality issue... this head was intended to go on my car with that bottom end however certain financial issues arose and I cannot get it
