Smile 7500 RPM 302 Stroker Suggestions

Hello!, As the title says I'm looking to build a 302 Stroker capable of 7500+ RPM at 450ish horsepower. The car will be used occasionally on the track, for autocross, and spirited driving on street come weekends. I've never built an engine on my own before, let alone something like this so I was hoping someone here might have some information/experience to help point me in the right direction. Money isn't an object as I'm looking to do this right the first time.

As for right now, I was looking at using Ford Stroker's 331 Liberator Dart Shortblock for the bottom end, with the Scat Cranks and Rods(or should I upgrade to the Callies magnum crank+ Oliver light rods?), flat top pistons, and the inline valve relief. For heads, I was looking at Stage 2 Canfield 192 cc with 58 cc combustion chambers, paired with Ferrea intake and Mahle exhaust valves, beehive springs, and titanium retainers. I am still unsure what style of camshaft, lifters, intake, or what compression ratio I'd I'd like to run (Suggestions are welcome).

Are these the right parts for the build/could they theoretically handle 7500+? I'm worried I might need a lighter rotating assembly, and with the pistons working with the Canfield heads. If anyone has used Ford Stroker and CPR I'd also be interested in hearing about it.

OR

If anyone has an engine builder they could recommend, I'd consider going that route instead.

Thanks!
