how do i identify 95 b18b1 cams from 90 b18a cams,they're both stamped pr4 on the cam gears.What are b1's stamped?i have a 90 b18a1 and got these cams cheap,and since my heads tore down I thought i'd put some b18b1 cams in since their slighty more aggressive. TIA

 

I think the cams should say p75????

 

so p75 can anyone confirm?

 

i have b1 cams in my engine and they dont say p75

 

what's stamped on your cam gears?i'm taking the head to be cleaned i guess the machine shop can tell me if theres any difference between the two sets,or can i measure some how.can't find any pics on here of b18b1 cams/cam gears.

 

i believe all b18s and b16s had pr3 on the gears
