X-Head Porting....

They have fixture stands for the heads, they consist of 2 upside down "U" brackets with tapered spikes welded to them. Once you get the hang of moving them for your comfort they work out well. As far as running out of air, get one or two old compressor tanks & put them between the compressor & your work area to increase the air volume. That way your compressor doesn't work near as hard.
