B18c5?

Aight i was checking out my buddies civic and its all souped to the tits, hes got a bunch done under the hood, i check the block and hes running a b18c5? Now i know the b18c1 is vtec, and so is the c5 but what is the difference and how much power does it put out?

TIm

b18c5 is the b18c1 block with a b16 head on it, along with a higher c/r (10.0:1 compared to 10.6:1) different cams, pistons header (jus to name a few) etc...

the c5 is originally from the usdm integra type r and puts down 195hp/130tq compared to 170/128.

Need some help. I have a b18c5 enging that i want to rebuild. i also have a b18c1 Tsleeve block differently bore to 81.5mm with 12:0:1 pistons, eagle rods and balance crank. I want to know if i can use the b18c1 block with b18c5 head. if so would it change the compression ratio? and what kinda power can i expect from this set up? thanks.
