looking for thoughts on head recommendation for a 360/426 stroker engine. the build is using the Hughes 360/426 kit, got the kit earlier in the week - nice stuff !
this will be bracket engine with around 12.5 compression and a solid roller.
tossed between the Hughes Edelbrock big mouth heads or the Indy 360-1 - cost is about the same just wondering if one has more potential or is a better choice ?
thanks

If the cost is the same, then go with the head that still has room to grow, which would be the Indy's.
How much power are you trying to achieve? Not many choices out there, but I personally prefer a cylinder head that moves the pushrod pinch.
I also wouldn't count on the cost being roughly the same. Indy stuff isn't always without hidden costs.

The Hughes heads are the CNC big mouth heads, 225 port volume that flow 320, cost of heads are 3200 plus their rocker gear your at 4k, this is before any spring upgrade for solid roller.. The Indy 360-1 from Indy is around 2k, the Cnc 245 is an extra 1k plus t&d rockers $1k puts it around $4k.. From what research I've done the last day or so. the Indys may need a little more attention.. Leaking issues, cracking. Etc..
Looking for 650 ish horsepower to put Scamp in low 10 class.

Check out the Indy Ta heads. They are what used to be called Indybrocks.
They are an edelbrock casting that the pushrod hole is moved out and standard 440 rockers are used.
I think the complete kit heads with rockers and a few other items is around 2500.

Don't know enough about the Big Mouth heads to say yay or nay on them. I would say Indy's since potential for growth is there with them, but have heard a lot of not so good about the -1 245 CNC on the exhaust...as in aluminum sprinkler system

I had these with there cnc porting on my 416 and they did very well as I was pushing right at 650hp but I do fell they where maxed out at that.
so no room to grow.

That's what I heard also, I don't have an irrigation system at home but I know I can get it done cheaper than than running 2 hoses to 2 useless 360-1's on my lawn, lol

650 should easily dip an A body in the 9's. Should be fun.
If that was my goal, I would run the Indy oval port head, and talk to someone like Brian@ IMM on here if he want the cnc done on them before he or another builder finishes them.
Your gonna have better rocker gear on them, an excellent intake for them, and more potential.

Glad to see you are doing your home work. I used the indy brocas with success but have had very very bad luck with indy otherwise.
Unfortunately they have a corner in the market. Maybe call eden rock to find out where they are with those victors.

Yeah I wish there was some news on the Eddy Victors,
My concern is that the big mouths are at their full potential, where the Indys may have more future potential , but I guess that comes with a price also..

My first question would be.. what block.. being I think
your talking stock block 650 would be about the limit
I would go or go with a R3 block then non of these
heads would be on the list.. but I might think about
talking to Hughes to ask some questions on their heads
like 320cfm at what lift but prepare to go above that
lift by at least .060 or more.. ask what kind of
spring pressure the rockers can handle... what kind
of rpm are you planning to turn

If you can run high compression, our ported eddy heads will make more than 650HP.
Typically, 13:1, our heads, cam in the 260's @.050 and correct supporting equipment will get 670's regularly...

That sounds SUPER optimistic with Eddie heads. Over 670 horse?
So that means 3300 pound cars are running 9.70 and 9.80's with them at 136/137 mph. Would love to see such a build and the on track results.
I know your a great guy and builder Brian. But if your going to make an outlandish. claim like that I would love to see a car with such a motor in it laying down appropriate numbers.
That's more than my WELL DONE 13 to 1 W5 motor made with much bigger roller, good ring pack and very good assembly. That went 135@3350 pounds..... Not close to 670.

While I don't know Brian's capability first hand I've made 627 hp from a MCH CNC eddy head with 11:1 and a 640 lift roller.

I think there could be more on the table with more compression and an appropriate cam change.
