Will there any piston issues with say just the average scat 4 inch rotating assembly

These heads have a 16° valve angle, and the valves are moved WAY over towards the ex. side of the chamber...CP will be offering these pistons as a piston and ring kit, dish, dome, or flattop, 1.2mm / 3mm ring stack for 949.00 which is a damn good price for pistons AND rings!
 
these bad boys should make pretty solid power

haven't even finished the magnum rhs headed 408 yet
but already planning my next build
 
Thanks for the correction again Brian and the heads up with the manufacturers for parts to roll with these heads.
 
Been a long rough road.... but I'm still excited to see them out. I'm afraid the cost may create some sticker shock, but IF they are a good casting (which many heads at this level have proven otherwise) I think they'll be worth it. Looking forward to the build Brian.
 
Most likely we'll be using a 3.79 x 4.08 engine I already have...the goal will be 1.8HP per cube...
 
Sticker shock, kind of yes, kind of no, here's why it's not.
By the time you get your regular RPM heads and have them
Ported out to the max, let's say a CNC job by Hughesengines, your into them for a hefty price with less performance.

http://www.hughesengines.com/Index/...&level2=RWRlbGJyb2NrIFZpY3Rvcg==&partid=26914
$1605 per solid roller Victor or $3210 for the pair
$2908 for the CNC version (pair)
$2847 for the big mouth CNC (pair)
Now go compare flow rates. Worth the money?
Yes IMO!
(And we didn't include valve springs to step up on the RPM heads or shipping from Hughesengines on the heads.)

I agree I would spend would the money

Intake flow#'s on 4.030 bore:

.100 70
.200 145
.300 221
.400 282
.500 310
.600 330
.700 345
.800 356
.900 363
1.00 367

No welding, they are cnc ported and the ports measure out very good IMO. On the bigger bore, they topped out at 385cfm at 1.00".
So far I'm liking them, but they are HEAVY!! All the whiners who hate cast iron heads for their weight are gonna feel pain in the lower region but all well ;-)

Do they come cnc ported or is that something you did?

Edelbrock will sell them CNC ported, with or without valves, and solid roller or hyd. roller springs. They also have a porters core with really small ports you can use to make your own port....I recommend buying them bare with valves...for now anyway.
 
I didn't see any spring rates, though I'll be honest, I didn't look to hard.

How much better are the numbers on 4.07-4.08 bore ?

Here is a direct comparison of Hughes' own flow numbers for the two cylinder heads in question. Taken from the hughesengines.com website.
-------------- Victor ---------------- "Big mouth"
---------- Intake--Exhaust ------ Intake -- Exhaust
Lift
.100 ------- 75.8 --- 57.4 ----- 77.4 --- 89.0
.200 ------ 167.4 -- 115.5 ---- 168.1 -- 139.2
.300 ------ 238.5 -- 154.1 ---- 236.4 -- 156.0
.400 ------ 296.2 -- 187.0 ---- 279.0 -- 185.0
.500 ------ 339.3 -- 212.3 ---- 304.8 -- 206.0
.600 ------ 357.3 -- 227.7 ---- 312.3 -- 218.0
.700 ------ 366.7 -- 238.6 ---- 319.9 -- 226.0
.800 ------ 371.3 -- 246.7

It's also interesting Compare OU812's numbers below to see how much difference using a different flow bench can make, Sometimes almost as much as 10% or 27.3cfm @ .600" lift between Hughes and OU812's results testing the same product.

What bore size did they use? The numbers go up noticeably with a larger (4.125) bore adapter and plate. My #'s are on a 4.030 bore and plate.

From what I can't tell they don't specify a bore size. it is mentioned that their bench is a SAENZ model 680 flow bench.

Using a 4.030" bore adapter seems like a good choice for simulating a more typical "real world" rebuilt OEM block scenario compared to a 4.125 which sounds more like race block territory.

I find flow numbers quite interesting, These Victor heads look to be putting out some VERY nice numbers, considering how they stack up to your RHS heads, which are a proven product and impressive by any standard.

For a side by side comparison. two high performance heads. Tested @28" and 4.030 bore adapter. Tested on the same bench. Numbers taken from WWW.IMMENGINES.COM

-------------- RHS ----- Victor
.100 --------- 69------- 70
.200 --------- 141 ----- 145
.300 -------- 197 ----- 221
.400 -------- 241 ----- 282
.500 -------- 267 ----- 310
.550 -------- 271 ----- ???
/600 --------- ??? ------ 330
I know it's not an ideal comparison since the RHS are nearly peaked just when the Victors are hitting their stride, but it shows some pretty amazing potential, especially strokers with cams spec'd north of .600" lift.

I'd personally love to see how this comparison would translate to a real world scenario. Since the flow difference is pretty huge from .300" onwards, I'd be interested to see how they would compare in something like a fairly mild 360ci mill with a .620"-.650" lift roller cam. starting with the RHS cylinder heads and dyno it as a baseline and then swapping the victor heads for a back to back comparison.

We are planning just that...testing these on the same engine we ran the Indy iron head on to make 606HP!
 
This is how things can vary. W5 heads;

I am testing the victor heads a superflow 600 tomorrow. I will post the results and video the test.
