How can I tell if they are Skunk 2 Stage 2 cams? Should they have a stamp on them or anything? I looked at one of the cams and it has a 2 imprinted between the cam lobes but i'm wondering if there is any other way to identify these.

 

H08 in/H08 ex on the ends...there is a letter 'm' i think around cyl #2.

 

measure the intake vtec lobe with a caliper, is it more than 37 mm?

 

anyone else
