demon, i live on your page. i am not really wanting to do the complete job myself. i'm just not comfortable enough to ruin a perfectly good set of heads. even if i will get another brand new set when i buy my 3L. i am just wanting to get the major port modification out of the way so that it will not cost me as much to pay somebody to finish the job and give them a proper porting.
to answer your question mapoftazifosho, these are oval port heads that are being modified to work with the split port manifolds. i have the split port gasket sitting on top of the head to work as a guide. all i am using for the port work is a couple of burs that are designed to work on non ferrous metals.
