Honestly anything that will be stock shortblock is best with a TFS Twisted wedge head. I say that because its the only head that will clear stock pistons with 2.02 valves and even a small cam and can be ported to support 8-sec power down the road if needed.
I personally wouldnt waste time swapping on a GT40 head.

Not only did I fail at building a fast mustang but I bought a yellow zo6 cause I couldn't get my little dick up.
Yeah? How often do you lay into the full 600+ HP?
I think some of you got compensation issues.
I just think it's hit or miss with different cars. There really is no magic number of where you'll grenade these things. Some can't handle 450hp, and some are like the above mentioned car. Arguing over it is pretty much pointless.
He does very often, trust me.

I agree with your entire statement.
But good engine designers don't build on hit or miss.
And they especially don't build on urban myths!
If you're feeling lucky, go right ahead!
Just be prepared to Fail...
Another data point is a buddy of mine's '88 Notch, AFR's, small cam, Systemax intake, S-Trim, spinning the tires above 5300 made 430+ on **********'s dyno (I suspect it makes much more without the tire spin), has been put through torture like this all year..

And this is the shortest hill we run. At Duryea this past weekend this car was basically WOT for the entire 2.2 miles. Holding together, stock block, safe tune, good fuel.

Cool... vid.... (and Duryea is the bomb!) ;)
WOT isn't the issue.
A run like that (or a dyno pull) is at max RPM/HP for a brief time.
Nothing like a long charge, say the big end of a 1/4 mile.
Generally, you get away with RPM, HP, or detonation.
But any combination of the three is a problem.
Yeah, you can tiptoe 500 HP and beyond with a stock block 5.0
I just don't tell friends, you-can-do-it, no problem!
Huh? Did you watch the video? Giants' last straight is a 1/4 mile, 22* incline, at WOT. The beginning is basiclly a 1/4 drag, up hill. He is going into T1 at 120 mph. How is this easier on an engine than a single 1/4 mile run?
Duryea has a .8 mile finish, uphill, at WOT. This is after over a mile of constant WOT, to lift throttle, downshifting, banging the limiter, etc.
You've run these hills, haven't you?

I have raced Giants and Duryea many times.
WOT against up a hill around turns is not sustained WOT at maximum RPM+HP.
Honestly I don't care to argue what you can do to a 5.0 before it blows.
Shall we talk about how they often crash when they blow?
Anyway, it's your car, do with it as you like!
Naturally aspirated HP is my thing.....

OK, so TWO Wide-open throttle 1/4 mile straightaways, uphill, with 1/2 mile of turning in between them, on/off throttle, is easier on an engine than, ONE 1/4 mile straightaway. Gotcha.

Hey, if you're trying to impress me, it ain't workin!
Anyone can build a hand grenade boost motor.
Sometimes, they even stay together!
Impress you? What are you talking about? You are saying that one flat 1/4 mile is harder on an engine than two that are uphill. You are making no sense.

It's because you're not smart enough to understand me.
Smart enough to understand what? There is nothing to understand, you haven't made an intelligent argument in the entire thread.
You accuse me of trying to impress you so you go out and find a video of Merlin Miller, from the hillclimb I competed in over the weekend mind you, like that shows something.
Who are you trying to impress? How about you post the times you have run there, and then I will. Will mean a whole lot more than you name dropping a full tilt GT-2 car owner. Of course it is fast, it weighs 2500lbs and has 600hp. Big surprise. He got FTD this past weekend too.
Dude if you have a problem send the god damn parts back. Already told you I would send you your check, I have it in my hand ready to drop in an envelope. You paid 100 bucks (and I paid 13 dollars shipping, so $87) for camber plates and a bumpsteer kit. I practically gave you the parts. Seriously, I will eat the shipping, send them back to me.

You boost guys are so grandiose you miss half the sport!
All you do is point and shoot! Point and shoot! All it takes is big balls.
Tweaking a few HP from a high strung NA motor, or a few tenths off your time,
takes real thought, real engineering, and real driving skills.
But you're not so worried about that!
Here you go, Duryea Hillclimb times
2008: 1995 BMW M3 (NA, near stock)
124.9 first time ever at the hill
2009: 1995 Ford Mustang (NA 302, carbed, home built)
118.6 broke after a few runs
2011: 2009 Chevy Cobalt (2.0 Turbo, stock with tune and tires)
122.1 DSP record broken by 12 seconds
Wait, didn't you run in DSP? What was that thing about driving skill again?
