X-Head Porting....

PRH said
If the X heads are unmolested now...... the value generally goes down after a diy-er has whittled on them.

Unless you find you have a “gift” for head porting....... it’ll take more practice that just futzing around with some old cores for a few hours before you’d really be ready to properly go after the X heads.

X heads are unmolested... besides painted... I wasn't planning on selling the heads, so wasn't to worried about the value ... just looking to pick up some extra air flow from them, nothing crazy. I have pictures of them somewhere..

I mean I work with a drill daily... but usually work on much smaller surfaces eith a much smaller drill...
