help with newer top end combo

[Project86]

So I recently pulled my current combo out for all new deals and gaskets.
It's a .40 over 350. With a Xe268 cam. 993 heads stock performer intake and a Holley 650
I've had this big cam sitting for a pretty good while.

It's the 305h Magnus cam and lifter set.

I have a friend of mine that has some ported/polished a d worked heads. 882s I believe. They were on a 11.5-1 roller motor. Guide plates screw in studs etc.

I'm thinking of throwing in this 305h cam. Getting a Victor jr intake using his worked up heads. And installing a 3000 stall in my built th350

Is this a bad combination? My CR i would venture out to say is around 9.5-1.

I know it's pretty much a bracket racing cam.
But would it be ok for a limited street use truck?
