Yes Jon, you got me drooling indeed...

I don't know anything about Hemis, but there are tons of aftermarket heads available, so it makes me wonder, how different are the Neil & Parks heads from other high end heads like AJPE and such?

What's the typical % nitro used?

JrFuel Hayden:
NHRA Heritage JrFuel, & A/ND, B/ND Comp rules limit to CAST IRON only heads, you can use alum heads in everything else, except SouthWest Jrfuel Association, iron only.
ALSO NO NITRO in the about classes, alky only.  Bracket dragster classes can run any nitro, alky, or gas, & of course blowers too.
I hope this clears up some of the confusion about JrFuel. You can find more info in the NHRA Comp elim A/ND, B/ND rules, and Heritage JrFuel rules.
There is ALWAYS talk about a real Nitro JrFuel class, and I have suggested, many times, that if anyone wanted to build a nitro JF car, they should and race it in 7.0 Pro, and when they have 10 cars/ teams then I'm sure we can talk Heritage into making nitro JF a class. We just need enough car count to make the Heritage tracks happy.
So, I say it again, BUILD IT, RACE IT , find a combination, and let me know so I can sell the class. Gary Adams, Gene Adam's, brother tried to put together a injected nitro class with the main idea of a cost limiting rule of only Vertex Mag, instead of fuel pump limit like Heritage A/FD. Big fuel pumps with out enough ign will limit the HP and costs. But no takers, Gary even had a race booked, but no cars showed except Kin Bates 6 time Heritage A/FD Champion, with a Vertex mag. 
Included photo is my 1963-68, 301 ci 97% Nitro, all iron, high gear, smoke the tires till half track dragster. We won allot in the Midwest, ran speeds of 191 mph, in 64-68. And raced almost every week if there was no snow on the tracks, had a GREAT Time, back in the day.

I did not know that the modern JrFuel cars were nitro-free.

Thanks for the education Jon.

dreracecar:
Hey Jon, any dollar figure on that engine yet???????
Didnt Jim Paul had iron Buick heads available before GG's OK'd them for Jr.Fuel ??

JrFuel Hayden:
Bruce, GoodGuys got scared off by Jim Paul's lawsuit, so they OK'd the Nascar Iron version Buick heads. But there were no heads to buy.
Jim could only make a few heads before the alum molds broke.
Frank Parts at 1'st said $70k, for a complete motor, with-out mag and injectors. I'm sure he was thinking of what a good Comp engine would cost from a pro race engine builder, but he may be thinking closer to $80k now with all the work that has been done to the block. I didn't ask him yet what just the heads would cost, but they are for sale.
Most everyone doesn't know how much time and money it took to create this motor. It started about 10 years ago when Frank was pissed about the QC on the New Zealand made Pro Action 14° iron heads, so though "can I make my own iron heads".
So he called NHRA, "what can and can't I do?", they gave him guidelines, then Parks gave them drawings, blueprints, then NHRA said OK, now send us a head, so $10k later for tooling, NHRA had a head. NHRA approved the "replacement Hemi " head for A/ND & B/ND for 2009 Comp racing. And since Heritage uses A/ND & B/ND rules for JrFuel, Frank and Scott raced the 1'st time at the 2015 March Meet.
Their own designed head is only half the story, allot of design and work on the block in order to make it all work. Like the OE 331 block doesn't have enough iron in the lifter area to use a 60mm cam and over one inch lift, work, work, work !
I tell ya it's something to see and hear.
