Ok, a little off topic but since i did rent the tr7 head honco, I thouhgt i would post that I used it today to pull the RH head on the stag...This tool is da bomb. With 5 stuck and coroded studs, it pulled the head with no problems in about an hour from start to finish. I then removed the studs with vice grips.
Ready to move on to the LH head in the next couple of days if I can find time.
