SR solid lifter conversion questions

First post so take it easy on me

I am planning to go solid lifter conversion as well as dual guide on my s13 sr20det in my s14.5.

My biggest question is what are these modifications that people keep mentioning about the rocker arms needing to be machined for the solid lifters, i understand that the right tip of the arm need to be machined for a guide. I haven't found detailed instructions, if they're already going to be machined for the dual guide I can have them modified for solid lifters if need be.

My next question regards the springs and retainers. many threads run BC Ti retainers and springs including the NICO 9,000+ rpm thread but I believe codyace called them junk or garbage when he brought up JWT s3 cams, (I'm likely running tomei 260/260 solid type). I've also seen posts saying that BC retainers are harder than Tomei and others lending itself to longevity.

What makes other retainers like tomei so good that the retainers alone (389.95) cost almost double what the 90LB springs and Ti retainers from BC cost combined (255.96)?

Do oversized +1mm valves really have that much of an impact? wouldn't mind a lopey idle and I'd appreciate the top end.

At the end of the day I want a high revving reliable ~350WHP sr. I have have good compression but plan to go forged internals with ER spec package from enjuku as well as go full standalone. I should be running a t28 but Im not sure whether I'm going top feed or side feed.

Can this make 350 wheel reliably?
