Default low dyno result???

I know this is probably a "rookie" question, but does this dyno not seem low for this combo? I was expecting an honest 575hp+ out of this, but the engine only pulled 540@5900rpm.
maybe with a carb/intake change, 575 can be achieved...

428 + .060 = 440cid
74cc KRE 326/525 heads
11.0 : 1 compression, 210psi (hot)
255/263 @ .050", 108LSA, installed @ 104, 594/610 lift@valve
solid flat tappet camshaft, .016" valve lash
torker II, matched to fel-1233, HP 830cfm Holley
Hooker SC 1.75" primary, 3" X-pipe exhaust
MSD Pro-billet distributor, 6AL, Blaster2, 31deg timing

I guess my question is...is the TorkerII and 830HP hurting me that much?

Btw, if anyone knows, is KRE's "house HP950" just a stock HP, or is it modified in any way?
