9.60 and 59 Degree are the simple and easy way to go.
Measure before purchase as NOT all 59 degree are 9.60
several of mine ARE 9.20!

Thank you. A couple questions. The cam bearing holes are huge. How do I address this? and how exactly do I measure the deck height accurately? Is there a part number to look for? If I buy a 48 degree what is involved in making it a street engine? Thanks again John.
