Neo Valve Springs And Retainers

[AngryRB]

Just a quick question, i have a neo head getting reconditioned at the machinist and bought some 260 9.15 tomei poncams to drop in,

Initially was told as long as the springs are the same height when measured that they should be ok which ive been told they are, but now told that the retainers are a high risk piece that will likely crack and ill drop a valve, so i should replace the springs and retainers with quality stuff like supertech... this makes sense but plenty of unopened RB's around and usually its a blown ring landing i would of thought.

Goal with build- area under curve 320ish, street car, 20psi max/ 14psi daily, 6500rpm limit, stock RB30 bottom

So is all that true or just trying to work the bill up???

The old 'you need this and that' trick lol.

They are more likely to spit a shim hey! but with the poncams you picked, you'll be fine.

You can get upgrade springs over there from Spool for a Neo with titanium retainers

Should do the trick no ?

[AngryRB]

Went with performance valve springs and titanium retainers, should be bullet proof now

Can I ask where from? And are you leaving the buckets stock?

[AngryRB]

Just a local place in AUS, yeah buckets are stock..

Believe they are the same ones spool sells?

Sure are..

Don't mean to thread hijack but what would a well setup neo head with cams, Springs, retainers and correct shimming happyily rev to? Would 8500 be a big ask?
