350 sbc upgrade PROMAXX project X 185CC tiny hydraulic roller.

Customer brought in a 350 he bought for us to look over and dyno test. The engine was in good condition it just didn't make any power so the customer asked us to do a bang for the buck upgrade with the stipulations of having a near stock idle and using as many of the existing parts as possible while still improving performance dramatically. The engine was already bored .060" to 360ci and internaly was obviously rebuild with very little run time so we installed a set of promaxx project X 185cc heads and a very mild 215/230 @.050 .475/.490" cam and reused the edelbrock performer intake and holley 670 street avenger carb and picked up 147hp and 73 ftlbs of torque. This will make a night and day improvement.

Were these out of the box heads? Or did you put in a better valvetrain? Also did you use 1.5 or 1.6 rocker arms?
