Whewwww..... tough to read without any punctuation, but I think your question is "will an aftermarket cam, lifters, pushrods and roller rockers for your stock 350 F-Body engine work in the 350 crate motor?"

The cam and lifters, should fit fine. Whether the roller rockers work depends on the rocker stud diameter.... but the studs could be changed if necessary. Finally, when you get it all together, you would have to check the pushrod length to make sure the length is correct.

Some other questions:

-Are the rocker setups on both engines "self-aligning" or "non-self aligning"?
-Will the springs on the crate motor support the aftermarket cam lift, taking into consideration the ratio of the roller rockers?
