OK...I have a quick question. I have a head for my B18b sitting in my room with Crower valve train in it. I am JRSCed, but I think this question would be better for you guys.... Once I redo my engine this summer I am upgrading my internals to handle more RPMs, so I am curious where the stock B18b valve train starts floating and causes interference problems? I will run the Crower head if need be but I wanted some info. BTW...I am running the stock cam. Thanks, and please don't flame for the wrong forum. Thanks

 

anything over stock redline or larger cams id upgrade....

 

Thanks...anyone else have experience?
