Solid roller cam?

[Five0]

OK when I talked to comp cams they told me that I would need to grind down the place where the bar on the lifters are or it won't clear but I have never heard of this and I may have misunderstood what he was talking about.

I already have a Vic Jr sitting around but went back to the performer rpm until I get another cam that will take advantage of it.

I planed to get a solid roller cam, solid roller lifters, 1.6 roller rockers with 7/16" stud (chromemoly steel pro magnum), stud girdle, and springs.

I have already got good valves and keepers (I just had them changed).

I know the cam I have now is too small, it was the cam I used before I got the 347 but have not had the money to change it yet.

The specs on the cam the told me I need are:

242/248 duration @.050
614/621 lift
110 lba
Cam specs

They have a price for the cam, springs, and lifters for 792.95 and 289.00 for the rockers. I will also need different pushrods, I think.
