LS VTEC SWAP Help!!!!!!

[98 CivicEX Ls/Vtec]

I have read for hours and hours online before my swap but i guess not enuf cuz i just finishing purchasing all parts for the swap and am realizing that i did something wrong,Ok first i have a 98 civic ex with d16y8 {sohc vtec} was racing hit a rock in the road crushed the oil pan since i was lowered blah blah blah the engine fried so i bought ctr pistons wrings pins rods cams and valve springs also arp bolts and obvious other thins also spent 1100 on a b17a crank to solve the bad r/s issue so i definetly am not doing things cheaply however i bought a p72 ecu which i just became aware of is both obd1 and 2 well the one i recieved was obd2 like my 98 civic ex but the head i bought for the swap is a 95 b18c1 so what i need to know in full is what is the easy way out of this i have run out of dough like Joe Pesci in Casino and i have completely no idea what to do anything will help trust me email me with anything or post i will try to check everyday.

Thanks so much to the ones responsible for boards like this one,
