Well in this thread: https://nastyz28.com/threads/the-best-chinese-heads-that-i-have-seen-to-date.334943/ I got ahold of a good set of cheap heads. After receiving the first set of heads, I bought 2 more sets of what was supposed to be the same heads. These were certainly not the same heads. Before I return them, I figured that I would measure a thing or two on them and snap a few pics. Intake port at pushrod pinch-> 1.990x1.05 Intake bowl measured at center of valve guide-> 1.960 (big hump comes in right behind where I measured it at) Intake throat-> 1.803 (89.2%) Exhaust bowl-> 1.377 (86%) Exhaust throat-> 1.380 (86.2...yes bigger than bowl) First off, these are just ugly. This is the first set of the new generation of procomp heads that I have held in my hands. I have bought several different sets of Chinese heads over the course of the last year, but never had any interest in these because of the way that they look. Silly, I know but im just crazy like that. They just look cheap. These seem to have the same "ridge around the intake valve" problem that the flotek 180's that I bought had out of the box, albeit not quite as bad. The valve job is pretty sorry. It is not a radiused valve job by any means and there are just sharp corners where the angles come in. Not inconsistent with what I usually get on Chinese heads, just FYI. The first thing that sticks out is that there is a MASSIVE hump in the casting where the head bolt hole goes through the common wall. Then looking down the port, the roof is as flat as a board. No arc of any kind leading into the long radius (roof) of the port. The bottom cut of the valve job is blended pretty well and symmetrically to bowl, but there is some funkyness in the short turn area (left side in the pic) where the huge hump starts to protrude into the bowl. Port alignment shift is pretty consistent with what I have seen on the Chinese stuff. This is a 1206 in the picture that has been trimmed on the top a bit. I meant to measure how much material that there is in the pushrod pinch area should you want to widen that...but I forgot to do it and I don't plan on getting them back out of the box. I don't have any interest in keeping or porting these. I think that it would take a ton of work to make them "good", and I don't expect them to do much out of the box after looking them over.
