I actually got the head off a guy with the cam for £150. When it went in for some more work it had two bent exhaust valves, I was gunna switch them out for some I had off my original head. Found out they didn't fit, measured all the valves and realised they were all oversized. Out of all the TSR head (knew it was a TSR head) the pack d was the only one with the same sized valves. Pretty lucky tbh. The agg bottom end gives tones of torque compared to the 1.8, find myself going everywhere in a higher gear.
