i got a gsr vtec head from a friend of mine and he stated that the cams are stage 3 turbo jg cams, i have checked the cams for markings, they are stamped JG but there is no number like 303 or 236 ect.. as other people claim to have stamped. i am wondering if anyone has seen this before? they look pretty aggressive. did jg make cams without stamping a number on the end of the cams? any info is greatly appretiated.

 

JG still in business? Call them.

 

They never answer

 

Nobody?
