All-
I have a 67 Barracuda that I road race with different sanctioning bodies in the midwest. They are coming down hard on certain 'non-period' car mods now. I have ported Edlebrocks on my 340 currently and have been given a grace period to replace them with iron heads before I will be failed at tech and not allowed to run. So, I am going to set the current engine aside for my 71 Scamp project and start fresh. I have a 340 block, Milodon 340 road race oil pan, and McLeod lightweight clutch and flywheel that will port over to the new engine otherwise I'm starting over. Strokers are out (yes, they can check displacement at the track). I hate to lose the Eddys (CNC ported and flowed around 300 @ .600 lift - current cam/rockers net about .610 lift) but it is what it is. Crank, rods, pistons, and cams are open (as long as the stroke is factory). Roller rockers are ok but not roller cams. My big question is the heads. The engine will spend most of its time between 4500 and 7500 rpm. I know people have gotten the same or better flow numbers porting W2s as I saw on my Eddys - is that the best / only choice? Yes, I know that means intake, headers, and valvetrain need to change and that's not the end of the world. Since the heads are where I'm shackled the most I figured I'd start at the top of the engine and work my way down as far as putting a package together. The goal would a comparable (albeit heavier) version of what I have now - a reliable long block putting out something in the 450hp range. I'd take more for sure but I'd rather build something with a little more safety factor (ie - not wound to the hairy edge). Our race weekend usually nets between an hour and two hours of track time and I typically get 6-8 events (2 seasons) between freshening. Thanks in advance for the input.

Stock magnum heads can put out 400hp untouched.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Obviously, from a power production standpoint the W2’s are going to be hard to beat.
IMM might still be doing something with a cnc ported LAX head, and then you could reuse all the other bits that go along with the E heads.
For road racing, the down side to the LAX’s is they’re pretty heavy.
There’s a post over on FABO right now where Jesse at RAMM built a 340 with a solid cam and some warmed over X heads that made over 450hp.
My old 340 with ported 587’s made 478hp....... so it’s doable with stock heads.

What mods to the heads are allowed? This may not apply but 2 of the quickest NHRA Stock eliminator 340's in the country run 051 heads. The Super Stockers run highly modified 308's.

I would buy a set of the W2 race heads, not the econo versions and have them ported and set up to flow as much air as they can get without comprising the casting to avoid cracks while road racing I built a pump gas street and strip 340 with a forged steel 4.0 inch stroke many years ago for a friend of mine and member on here with a set of the race W2 heads mildly ported and polished, it made a little over 514 HP at 5900 RPM on CA pump swill on a stingy DTS engine dyno back in the early 2000s He drove that motor all over including several of the Hot Rod cruises from CA to back east as well as driving in the one lap around America once Those heads did everything my friend wanted and then some, he ran NOS on it also

"They are coming down hard on certain 'non-period' car mods now."
Will the Magnums pass the period visual test?
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

Will the Magnums pass the period visual test? I would think so. I think since the Magnums and the W2s have Chrysler casting numbers on them likely nobody would ever say anything. There are so few mopars road racing that nobody is really sure what they are looking at. Doesn't take a genius to spot aluminum vs. cast iron though so that's their big sticking point.

If they are looking at the heads, the W2's look more like a standard head. The ends of the Magnums have a different appearance. Maybe all they do is check with a magnet to verify they are iron?

I sure wouldn’t want to spend a bunch of money on heads and valve gear that you know aren’t legal(aluminum), especially when the tech guys have already told you they don’t want them on the motor.
I’d want some clarification on exactly what is and isn’t legal if I used anything other than period correct oe heads.

Agreed. I'm not a racer but I would assume there are few things worse than failing tech and turning into a spectator.
