This is RLZ's old N/A race car head. It's a GSR head.It has been ported, not sure what "stage", but it was on their race car, so I'd assume it got whatever goodness that they could inflict on it. It has Ferrea valves, 1mm oversized on the exhaust, titanium retainers, new springs (not sure what kind of springs RLZ uses), and the whole valve train is almost new (less than 200 miles). I just had it cleaned up and checked out and it's like new and ready to go. The oil feed passage has been plugged and it has an external oil feed fitting for LS/VTEC. I bought it when I was going N/A, and am selling it now that I'm getting a supercharger. This head is totally inappropriate for a boosted motor, don't even consider it unless you are building a N/A motor. It has been cut until it has a 35.5cc chamber volume, for what that will do for you CR, please see:
