How do I idnetify what type of head I have and where I can located the number? I have a B-series head but I dont know what type it is. How do I also identify what cams I have. The guy I got the head from seperated the head and cams so alittle help would be appreciated. TIA!

 

Type-R and B16 heads have PR3 stamped on them. GSR heads have a P72 stamp. LS heads have PR4 stamped on them. There is a thread here somewhere about cam identification-do a search, and you should be able to come up with it.

 

Thank you bro!
