Greg,
There are a couple things you can do.
1st- you are using a jobber cam,get a good comp cam.
2nd- use only Crane cam lube,thick black moly paste.
3rd, use Shell rotella 15W40
oil ,it has the additives in it,after break in use 1/2 shell and 1/2 pennzoil 10/40
oil.
4th- If you are using stock non adjustable rockers you MUST check the lifter preload clearance.
