Re: b20z bottom, gsr head (Booger's_Rex)
If you ar using a GSR head you are completely fine. The GSR head has 31mm valves where as the B16a head has 33mm valves. The pistons in the B20 have valve reliefs for 31mm valves therefore you are cool with a GSR head. If you use the B16A head the only problem you will encounter is that you cant advance the cams more than a few degrees or else the valves will tap the pistons. Hope this helps some.

dont mill the head
and you might have problems with the ITR cams if you advance your timing more than a degree or 2
while the head is off the b20, cut the valve reliefes 2-3 mm
