BTW, speaking from experience (having pulled the motor for a rebuild on no less than 2 occasions, sigh) there's almost no scientific way of figuring out where ticking is coming from. Not with the reverb halls that are our aluminum blocks. I've had tens of experienced mechanics and engine builders try to figure out the issue from above but in all cases were wrong. Pulling things off is sadly the best way.

I'm also always confounded by shops that sell kits with light titanium retainers, lighter rocker arms etc etc, designed to lighten your top end then slap on a massive/heavy dual valve spring. Makes no sense to me.
You can get lighter duals or good singles.

While this is true, 145# of close pressure is extremely higher than the stock 95#. On a lower lift cam with boost he should need to run more than 120# of closed pressure. too stiff of springs will cause failures.

Correct. 120 on the seat and under 400 open is what you should be aiming for.

Patriots for example use titanium retainers that are considerably heavier then a set of PSI springs with titanium retainers.

Expensive lessons these.
