So, will these heads not work on the gen 5 block, or what can be done to make it right if anything? Is this parts list for the 509 or the 540 or is it the same for both?
Here's the dyno sheet:

your better off following these builds to get real 700hp engines.

LOL...so for a 540 with open ex they were only able to get {{{720}}} hp (whatever the {{{ }}} means) and 645 tq? ...and with a peak @ 6600???? That engine is an embarrassment. The numbers on the "dyno sheet" are all jacked up. It loses 7 hp from 6200 to 6400 but then miraculously picks up 9hp @ 6600, then falls off another 11 from 6600 - 6800...and love the dual torque peaks. LOL...and that's your idea of an exemplary engine??? The SuperChev 540 isn't any better, either. Certainly not worthy of another 30 ci and 1/4" of stroke. Nothing more than magazine fodder to impress the masses.
You guys are a joke. Please, there's no room for your input here on engines.

why don't you post your miracle 460 or what ever it was that you claimed 900 HP with rect port heads

You clearly missed the sarcasm. But hey, we can use your dyno sheets with 20% correction and call them good. or how about you friend voodoopro and his 40% that you say are great.

What I find interesting, is guys like Scott Foxwell, and many other "professionals" in the business, chime in on many different forums, posting pictures of heads they may have ported, combos they put together, general engine advice, blueprinting and machining info, camshaft and valvetrain dynamics, public videos of valvetrain mockups, induction debates, assembling procedures, and so on. Basically, putting it out there publicly, among some of THE BEST engine builders on other forums, wide open for criticism. And yet, YOUR HERO, reads all these forums, is a registered member of all these forums, and yet, never has anything to say. I'd like to see HIM, jump into the fire, and argue his valvetrain theories, and engine design expertise, with guys like Mike Jones, Chris Uratchko, weingartner, curtis boggs, darrin morgan, and literally hundreds of other engine builders who build engines daily......where is his public advice on those forums, about which intake manifold works best, which cylinder head works best, which is his preferred brand of ring filer, valve cutting machine, and so on.
Sorry, but its 2015. Anybody can figure out a decent combo for a big block chevy engine, when you study hundreds of other peoples engine builds. Want talent? Walk into a shop that can build anything from a 4 cylinder nissan, to a resto 340 mopar, to a blown alky dragster, a 1500hp pontiac, twin turbo LS or yes, a 900HP 460ci, all under one roof. Its easy to sit back and quarterback everyone when you are on the sidelines, rather than in the game.
Sorry buddy. This isn't boatfreaks, you don't run the show here. People here might actually have an opinion that doesn't agree with your camp's long lived infatuations with each other.

I don't know him personally, but I can tell you, him and his partner nailed the combo on Kevin's 572 build, and dyno testing was done on an independent dyno, in michigan. They also seem to have quite a bit of happy customers on yellow bullet, performance boats, and speed talk.

About the only part you got right. My cats can build a BB and get more HP out of it than stock. and do it without a 20% correction dyno.
