Your going to be asked for more information, you didnt put LSA or ICL.

No one will be able to tell you if it will clear or not, you are 100% responcible for checking NO MATTER what anyone says on here ever!

The MS4 is built to have adequate clearance in LS1 applications with stock cylinder heads. With hundreds & hundreds of those camshafts on the street you can rest assured that there is absolutely no p/v concerns with our MS line of camshafts.
