Exhaust side flow ported 243's
 
Anyone know if any of the vendors will CNC port customer supplied heads and is so how much?

I have a set of 243 castings that were hand ported to some respectable intake numbers but there is quite a bit of potential left compared to the flow numbers of some of the CNC programs I have seen advertised especially on the exhaust side compared to my heads.

Or would I be better off having the exhaust done by hand and if so by whom and cost vrs CNC.

Talk to Total Engine Airflow or Advanced Induction - they both work on customer supplied heads.

Where are you located? I just had a guy hand port and polish my 862's and he got some really nice #'s out of them. I am in NC and I can get you his contact info - I'll Pm you with his name and number. If you're interested in sending them to him, tell him Brandon (with the 862's) sent ya.
