#355350 Hey Im building up my b18c1. looking for about 220 hp out of it (n/a). I need some good advice on what to do with the head to get there. Block has already been bored and decked and I will be running itr 81.5mm pistons.

#355376 220 at the wheels doesn't have to deal with correction factor. I would assume you're around 2500' in elevation which would take roughly 250whp corrected to be a true 220 whp car. Most tuners use a 1.10-1.19 correction factor which accounts for air density, humidity and other factors.

#355378 Close it's about 2100 feet and dryer than a desert lol. But anyways as for head work what should I be looking at to get roughly where I want to be in numbers. I realize 220 will take some work and money which doesn't bother me. I just need some pointing in the right direction
