Hi Cliffa , I would like you to take some measurements of the port ID if you have the head off. If you have the valves out even better. I will attach a drawing so you can see where the measurements need to be made. I hope you have snap gauges to measure the intake and exhaust port ID’s at 4 or 5 places along the port tract. Let’s compare yours to the MCT heads.

Hi Tony, I'd be happy to help of course, but unless I find anything wrong with the head I won't be taking the valves out, and unfortunately don't have a snap guage. (I may be able to borrow one though). I'm 99% sure mine is an MCT engine as well though.
