Mike, what size cam , what spring pressure, what size springs, these things can mean the difference between being able to use the Harland Sharps and needing the Jesel, T&D's. John

Harland Sharp seems to be popular with some builders but they aren't inexpensive either.I decided to go with an old set of Isky irons and have them bushed and corrected at RAS. Gus

the -1s take a offset rocker,don`t they?
440-1 harland sharp rockers are offset
I think he is putting -1s on and wants a cheaper offset rocker.

The Harland Sharps will work just fine, I sell tons of them and have used them for over 20 years. When you get over the approximate 800-850 open pressure, its time for Jesel od T-D. Some of the H/S will go 1000#, but not the Mopars.
You could just re-use your exhaust rockers and buy intakes only.
I am going to run my annual H/S rocker deal starting next week. I can save you on a complete set or price just the intakes, but I think you'll see its worth your while to get a whole set as opposed to getting individual rockers.
I will shoot you a PM.
I'll advertise my sale at the beginning of the week.
Thanks
Todd

ARI...those should have been fine. I have been running them for years on .780 cams and zero problems.
Do you still have the broken ones? I'd like to look at them if you dont mind..on my nickel.

Yes, they can definately fatigue. It makes more sense now that you mention they have "miles" on them. They are excellent pieces in my opinion, but like anything, yes they can break over time but I would have to assume they have had a more than useful life. I just dont see them break without an explanation of oil starvation, too much spring, binding conditions, plugged oil holes, over-revved etc.
I just took a set off a car last year that I know had 17 years on them. It did finally break one and it was time to call it quits.Put a new set on and hope the customer can get another 17 years!

Thats a good thought as well. EZ's and SRs also use the standard rocker set up you have.
The -1s will obviously make more power if that is in the plans later on.

if you want a head that you can kind of "grow in to", the 440-1 is the way to go IMO. those big peak horsepower numbers from magazine dyno mules means absolutely nothing until it's backed up at the race track. the simple truth is that the 440-1 head will make more power at any and every point in the rpm band on the dyno AND at the race track. they've been a proven cylinder head combo for over 20 years, why reinvent the wheel. that extra power is especially useful for the bracket and class racers that need the consistent E.T. and also want the big MPH. the -1 heads can really shine in that scenario. for the guys with aftermarket blocks it's a no brainer over the EZ heads.
even though they cost a little more, they're much more cost efficient in the long run, even with the more expensive rockers. now, with that being said, if your really budget limited, the EZ head "might" be a good choice, but the 440-1 isn't really that much more money. to the statement of "blowing the bottom end out, that could happen on a stock block at 700 hp too, it just depends on the block and the combination of other factors. guy's have been succesfully making 850+ HP with -1 heads for a very long time. in any event, the Harland Sharp rockers have served us very well over the last 15+ years and cost a bit less that some of the other offerings out there. i've never personally had one break although over time, any rocker will finally give way when the spring pressures and cycles exceed a certain point. i replaced a set earlier this year that were running on -1 heads for the last 12 years with 1.625 O.D, 850 lb springs. their was no appreciable wear on the shafts or the bearings. we put the old ones on a backup combo with less spring (650 lbs.) the change was made just to be on the safe side. one other point, the HS rockers clear a 1.625 spring on -1 heads without any clearancing of the rocker. the same can't always be said for one of the other popular rocker choices available, even ones that cost more. sorry this was so long winded. i just felt it needed to be said.

Thats not true at all. I do many engines that are not set on kill, are not looking for maximum power from their combination. Serious bracket racers want repeatability, consistency, forgiving packages that are also capable of going hundreds and hundreds of runs. One of my customers just sold his Duster, which was a 9.00 footbrake car. Could we have made it faster? Absolutely. Did he NEED or WANT to go faster? No. The class break was at 9.00 anyhow, so faster wasnt an advantage. The hardcore bracket guys look for reliable combinations, The street/strip crowd like typically likes to weekend warrior race. Many have there own goals, that sometimes is max ET, toehr times to beat there friend, and others just want it to stay together.
The challenge of building engines for customers is that you have to use your own intuition to determine what the customer tells you he wants, and what they really need and can afford. The two are quite often different. Not flaming you here, just explaining it is not always about maxed out combos. Many other things come into play.

i understand. it is hard to judge people even when thay say thay want it a certain way things change.my brother had a motorcycle shop for over 10 yrs doing tire sales to 700HP turbo kits.i helped around any way i could and have seen life from both sides.anyways i was just trying to coax him along.
