Danny_d19 is an unknown quantity at this point
It will fit, but it will lower your compression enough to notice a decent drop in power

Just rebuild your head yourself

Your best bet is finding b20a5 head, PK2 that is.

yeah they'll work but unless you plan on boosting the hell out of it then it isn't worth it, you would only get a 8.5:1 comp ratio with the B21 head on the B20 check out this link it shows the comparison between the two heads and what they make on the other block
