Kiwi HX

Hi,
I'm preparing to build a Gen 1 350 cid to go back into an old school Australian ute (the Aussie equivalent of an el camino)
Looking to generate about 400 hp at 5,500 rpm and 425 lb-ft.
TH350 with O/D unit, built for low end cruising, not looking to shred any tires or beat everyone out of the lights!
I think I have most of the parts list pretty well sorted out, but would like advice on AFR v Trick Flow heads and matching intake manifolds.

I'm really interested in everyone's thoughts and advice regarding:
AFR Eliminator 195cc CNC chamber and runners street head with 65 cc chamber matched with the AFR Eliminator Dual Plane 4150 manifold
v
Trick Flow Super 23 195, Fast As Cast, 64cc CNC chamber but not CNC runners matched with the Trick Flow Street Burner Dual Plane manifold

There's USD500 between them, AFR more expensive, but fully CNC heads.

Thanks very much.
James
