Just adding my name to the pile. As long as things don't change so much it goofs me up, as the rules stand now I'm putting something together to make an honest top 3 effort. I am, to say the least, anxiously waiting to see what the rules are for next year.
Conventional head design, is very simple to check in about the length of time it takes to lift the hood. Racers in the pits, all know who has what for heads... not even a tech needed for proof of that.
We can't get carried away with rules. We cannot force racers to be building to cylinder head lists, or any type of strict rule. Those days are long, long long gone........ it does not work in a sportsman atmosphere.
There needs to be diversity in the class to keep the spectator interest.
There also needs to be diversity to allow racers to use ingenuity and creativity within a broad rule structure, to be competitive, and not simply throw money with a given allowed strict combination.... where only the fat wallet wins. Obviously, we can't stop the big wallet from winning races, but a broad rule spectrum allows racers to think outside the box to give them an edge.... Not just pour another 10 grand of development into a set of junk heads that nobody wants anywhere else, to gain another .05 in ET.

Maybe....just maybe easy for most with a BBC, there are a few heads that could be questionable. But what about the other brands? What about small blocks. Is a 10* SBC considered conventional? or is on symetrical port head deemed non-conventional?
Not arguing with you Chris, just throwing things out there.
So Chris, the waters get just as muddy as with the SB. Victors have raise port and rocker rail, same with BMF's @.625". Yes most of the stuff is messaged to fit as well. The Pontiac head that rick mentioned has a dedicated intake, like some of these conventional heads, and to some that are not up on engines like yourself, they could look at and old Eddy intake for the "427" as a siamese port, much like Alans motor now, to an un-trained eye, they might think those are siamese ports. Now add into the mix the 18 deg. Darts and the TPS stuff, there's no way many can tell what there looking at, or if the port is raised without removing the intake and measuring from the deck.
Chris, pick up the phone and call down to Curtis and ask about the Canadian Conventional heads he just shipped a couple months ago, the water gets REAL muddy there!
None of it will run with a killer symmetrical port, or spread port raised runner BBC head.... so it's all about 200 hp less muddy, any way you look at it, maximum effort, to maximum effort.
No back at you, a max effort conventional head to a max effort head that Rick mentioned, will NEVER even be 200 with NOS! LOL. Yes a max effort 12 or 11 deg, head will make more, but Rick was asking about a totally different head and how it should be classed. And what configuration is that head he mentioned as it's not a typical spread port, noted by a different or custom intake, or a conventional head? It's like a semi-spread port 18 deg. much like the Dart 18 deg. ovals, as there is more of a spread port there then the 427's?
Ask Butch, he's done it. He lost on a red light to Alan, not on performance. My guess is he is just over 1000hp....but on ward and upward based on the top half being in the for sale section.
You know what it takes Ben. You show up with less than 400'' and make half the field look bad...including big chief headed BBC's.
I know what the power difference is between a small block @ 2900 lbs and a big block @ 3300 lbs to run the same e.t. I also know that the fast big blocks are all significantly over 3300 lbs because of scoops, 4 links, etc. I also know that if they are making around 1400 HP that there is a lot of reserve e.t. left.
let's say Between 20 and 40 G's depending on who's in your corner..... and For one their is no max effort ever going to be use'd due to the single carb or single throttlebody being used...the engine will never be happy running that way I know I had a 638 with the Biggest carb that was being built and made good power this was with a tunnel ram single I also ran this combo with two carbs and it really likes running with Two the only way to get more is with running "Fuel" or better heads The heads I ran were A-460 heads.....Thanks
