Need to buy some lifters for my 525sc roller rebuild.

Went with the Lunati 20110669 (629/612) cam in my gen 5 now I need a set of lifters.

I'm looking at the Johnson's 2112bbr or the 2116bbr, i need tie bars since I have a gen 5 but do I need the +.300 lifters or is it just marketing to squeeze more $$$ out of me?

I've also heard a .7 wheel like the Johnson's have, will take out 1.5 to 2 degrees of duration, this true?

Thanks
