.664" (.423" lobe), 11:1 My motor isn't going to use the heads full potential. just there in case I want to later. any ways I have the custom heads, mine can be ported even further and it has the dual plug capability

I agree completely with cre! The flow bench dyno nationals. They are just tools I'm running a .650ish" roller. 9.0:1 procharged.

Had a set of raised exhaust port St.V's done by Jeff @ MCH, 490 CFM int., 326 CFM exhaust. Was going to use .950ish lift and 15.5 comp but sold it all to go another direction

I gots me a .466+ lobe lift flat tappet from Barton that will go in first...Then a Old crane grind which has about .475 lobe lift roller. I say this cause i dont know what ration these rocker arms are, some say 1.6 some say less.
Compression is 14:1
Do i win a prize Dan-O for the largest flat tappet on the web site or something...
I guess it would be funny if I was running a .500 lift cam talking about all this flow.
well, if i was going to give you a prize for that flat tappet that'll end up around .755 lift, it wouldn't be anything to be proud of.
by the way, the S/R heads won't even come close to the power potential of the raised port big valve or millenium stage 5's.
the reason i asked about the cams and combo's is because the supposed 10 cfm difference doesn't amount to squat. until you build something of real potential, it's meaningless and not even worth worrying about.
for example, go ahead and run that silly flat tappet cam and somebody else running a well designed roller 10 degree's smaller with 10 less cfm will put you on the trailer. see my point?

Bob, you completely missed the point and instead your taking my comments as a personal attack or something. if you want to know why i think the cam you mentioned is silly, call me and i'll explain it to you. i guess if every post i make isn't a PC atta boy, you betcha, this is what i should expect.

Naa I take your advise very seriously Dan, I think honestly you generally want to help people, and offer good advise...
Ill keep the Barton Custom Grind "silly cam" (Bullet Racing).. He assure me he has some practice developing a max effort solid flat tappet cam... I would imagine he has spent more time on the dyno testing Hemi cams as about anyone.
Let me ask you this though... I cant seem to find any were in this thread where I posted any specs other than lobe lift..but your so sure that it's a poor cam choice, and yours would be better correct? How much time honestly have you spent on the dyno with a Hemi engine developing a flat tappet Max effort cam? He told me he has a fortune in scrap short iron in the attic with tested flat tappet cores.
He actually told me that it works with power brakes. LOL.. He was pretty secretive with the cam profile, and wouldnt actually tell me the valve events until I payed for it LOL.. He also told me this is the cam you get in a few crate engine including a 528 pump gas Hemi with 9:1 compression that makes 650+ hp on 87 octane fuel... I have also spent some time on the phone with Harold the cam guru that works for Bullet, that designed a bunch of cams for UltraDyne. He worked with those guys in this and a few cams developments.
Thanks for the offer though.
This will be my last post on this topic, and have talked with a few guys through Pm's about what I was trying to get across in this thread. (I will reply tomorrow guys).
In a nut shell, every time these MP heads are mentioned...many comments about how there junk, seats falling out etc...we have all read these comments. And I dont blame them for being mad or PO'd..But these are not no where near the same head, same casting, same machine work, or even from the same foundry as older versions. Thats all, just a good quality, cheap alternative hemi head...If not the cheapest available.

Thanks for the flow numbers. Does anybody know the following: - how much do StageV replacement heads flow out-of-the-box? - how much do Edelbrock/M2 heads flow out-of-the-box? Preferably the numbers from the same flow bench. Thanks.

i know which cam it is, and no, mine wouldn't be better since i wouldn't even offer one.

since i don't advocate any flat tappet cam with a lobe that big, the answer would be very little. what i can tell you is that i've pulled a large number of those "max effort" flat tappet cams out of hemi's (and wedges) that ended up with a lobe lift of around ZERO. they sure do make a mess when that happens. obviously not all flat tappet cams fail, (and i hope yours doesn't) but when they do, it sure does make a mess. the added expense of a tear down, cleaning and rebuild is quite costly.

okay most guys won't give out the timing events until you pay for the cam. there's a good reason for that. if your plan is to run 87 octane and make 650HP, good luck with your plan.
sorry to get off the main subject guys. i'll get out of the way now. please continue.

Dont forget about the newer MP/Edelbrock castings
These things flow a ton, and are the best thing out there for a hemi head that is a true SR type deal..stock valve angles, and port locations..
Modern cylinder Ported mine and got 460cfm from them.. The SR Stage V's wont flow that
I have all kinds of pics, and flow sheets..PM m if your interested I will email them too you.
i beg to differ i have a set from jeff that are in the same range as yours

I have a set of CNC ported Indy Legend heads. I have a solid street roller and 11:1 compression with single 1150 dominator. I am very happy with the overall performance of the engine and like a lot of the features of the Indy head. The only problem with the Indy heads is that you need to use all of Indy's stuff. Dram said to me once that if you use Indy's heads than your married to them for life. Well that makes a lot of sense since its true. If your not all that concerned about stock appearing then there OK. Indy's heads are much taller than a stage 5 head and also require there valve covers and spark plug tubes. Defbob let me borrow a set of stock valve covers and they look like they will fit but never actually ran it with a set to confirm. Headers are different and as stated in a post before, the chambers are slightly different. Allan G.
