I am looking into a cheap HC franken motor to mess with. I plan on squeezing a phase II 2.5 short block between some ej22 heads, the biggest problem i see at this point is that ej22 heads flow like concrete, the phase II ej22 heads arn't as bad as the phase one heads according to nasioc.

but i have a 97 so no phase II heads for me,

i have a choice between dual and single port heads, and the set i choose will be mildly ported so the biggest question is what Phase I ej22 heads flow better? where can i look up the valve size and other info on each head?
