i just got my b18a block today im so happy

I guess im the weakest link
lol i thaught the b18b had slightly larger ports.

i like when people don't take my advice.cause then i make more money when u need it rebuild the right way!
how many speed holes do i need in my bumper,b4 i can run 15's?

thay are the same head like you stated the cams slight change the springs are rated 9Psi more but it does lie in the ecu also sense it is Obd and not preobd its like compairing b16 to b16a2 10more Hp cause of the ecu and cam Yet the b16 as slight higher compression to the b16a2

The b16a2 probably got most of its +10hp from the cams, not really the ecu.
The obd0 PR4 has a little under 1 degree less advance @ 6200 rpm (peak hp) than the obd1 92-93 b18a. 1 degree is not going to give you 10hp.
