flatout

I am looking for a top end recommendation. I have twin sbc that are stock repowered in 01. I want a comrehensive top end recomendation on heads cam and intake combo. Here is what i have decided so far and others i am also considering. All of them claim roughly 400+ horse power. If anyone know where I can pick some of this stuff up used or reconditioned that would be cool too. I do have to buy 2 of everything.

this is the top of my list right now in order

Trick flow heads
Victor jr intake
comp cam 12-244

Edelbrock RPM pwoer pkg
edelbroch RPM head intake and cam

then the Holley systemax II kit
Holley Heads
lunati cam
holley intake
