Exhaust side flow ported 243's
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.
