I am finally about to get my GSR back from the shop this week. I ain't drove it in over a month. I slung a rod and it broke a valve and went through the block. I am gettin a B20b and puttin my gsr head on it. I got some kind of new valves can't remember what kind he said. He said they are coated and triple angled or somethin angled. I can't wait to get it back. I hate havin to drive my truck around which only gets 16 mpg.
