Changing brands of rocker arms may require a different length pushrod, too. When I was switching three different brands of rockers (Hughes, Indy/Dove, Harland Sharp) checking for the best geometry on a set of heads, none of them would have used the same length.
I have a set of Dove, Hughes, stock adjustables, HS and Ersons. None of the lengths are the same for any two of the above brands. A couple were close, but not "right" for both.
72 RR, Pump gas 440, 452s, 3800 lbs, Corked, ET Radials,. 11.33@117.72.
Same car, bone stock 346s, 9.5 comp, baby solid. 12.24@110.

This Saturday is turning out to be a Very special day for me. I'll be in the same room with some GO FAST "god's" lower case  HOLY CRAP BAT MAN  I'll try to take some pictures to share if they'll let me.  Dyno=Ultimate Man Cave

How much drop in HP to the wheels should be expected? Is it some mathematical equation? Engine - tire diameter, gear ratio, = expected HP@ the wheels? Just to get an rough idea what to expect? Is the only way to find out is using chassis dyno? Curious only and maybe some daydreaming

Correct, Motor Dyno. See the line "Daydreaming" I was advised that the 275/60R15 BFG's aren't going to be too happy!   Did I show you my Sonogram??  Thanks Doctor Dan!

well to answer your question, according to my challengers weight,ET, and mph my 360 was making around 535hp on the chassis dyno it put down 467hp to the rear wheels.

Which Harland sharps did you get? The ones you need are only available thru Mancini , at least they were only available thru Mancini , they are bushed on the shaft instead of full roller bearing.
JohnRR,
you are correct! Good call, that's exactly what was ordered.

Before I get Chastised about it.
It's an Edelbrock performer stock flat hood clearance intake manifold.
Why do I get the feeling that this is just the beginning of the Morphing of my car?  Why would I think that anyway??      
On a 440 yes it is,
You could probably squeak an RPM in there but you'll have to use a drop base air cleaner and possibly a shorter than optimum air filter height.
Ask Dan about a Street Dominator on that build , I have one that I may be parting with here very soon , that will give you a little more clearance over the RPM i believe ???

I have been purposly staying away from this thread because I hate the negativity thats thrown at anyone on this board that has the honesty to say they didn't buy the most expensive stuff possible. With that said: To the OP: I've had a great experience with my stealth heads. With no portwork whatsoever, they work great on my combo. I run ProComp stainless steel rockers. They are bushed at the shaft and have a roller-tip. I had a problem with them when I first got them with the adjuster studs breaking, but when I called Pro-Comp they fessed up that they had some bad adjusters get out, and sent me a new set of slightly different ones at no cost. No issues since then. I run them on a .573 lift solid. I've done numerous valve adjustment / checkups on them, and never found an issue. FWIW: you may have chose the wrong route with the RB Block in a 67 (if this is in fact going into the car in your pic?). Hood clearance is an issue with these cars, and that may keep you from using the correct intake for your combo (pssst: lose the performer, its gonna cost you hp.). Good luck at the Dyno, and with the car!

I'll talk to Dan on intake choices that would be worth at least trying just for the Dyno numbers. If it's not too much $, I will be glad to put up some $ to see it first hand the HP differences. (remember "Cha-Ching Cheapo" ) It would be a waste not to try at least one other intake manifold for numbers sake. Just some food for thought, Block was decked and intake fitted, it may not be that easy just swapping out another intake. I would have to have on on hand and ready to go in the AM at the latest. Do I see a Satin Black Fiberglass Hood with a 6 pack scoop in my future?

Theres a strong possibility that we may try a "M1" intake tomorrow just for numbers sake. As MOST of you MOTORHEAD guys know ,(and I am just now learning) a lot more goes into an Engine Build Recipe than meets the eye. I will be passing around the donation plate
