Canted for the win..

 

Im not sure. But there is alot of 12.5-13* degree heads out there that flow pretty well...430-445cfm W/2.20-2.25 valve VS> 2.3" valve/450-460cfm canted stuff. Hard to say.
I think it would come down to fuel being used and spark plug location. But what block are we talking?
Alot of the Canted stuff has a different Cylinder Bore spacing too.
IMO it would come down to the person(s) building the motor more than just a head change. Experience with what works with these different heads goes along way!

I have always been told that a inline could make more power but there are a lot of varibles!

 

nicely said!!!!!!!!!!

 

How many prostock engines are inline?

 

If dyno power is the only consideration, .. canted valve to some degree, .. and in some combinations it's not always a large difference.

However, sometimes an in-line head is proper for the application. Cylinder heads, .. port cross section, valve cant, delivery into the
chamber, wet flow, velocity profile, .. all of this stuff gives a head a "personality".
You can have two engines make identical power on the dyno and "race" VERY different on the track.

like so many other discussions on YB where it's attempted to make things black and white, ..
it's just not that simple.

I'll have to agree with this statement.

 

Two similarly sized heads with the difference being the valve arranement lends to the canted design every time. They will move more air thru the mid lift under the curve with the same cross section and valve size.

 

that a trick ? chris

 

canted head ? please-

spend money on getting the car to work and leave the canted selling stuff to head porters that know fuck all in order to fool you

Heeees baaaaack :-damnit

 

Do you want to go fast?

 

Even if the in-line head flows a little more or about the same throughout the lift range? I know the canted valve should have a flow advantage but if you take that away would it still have more power potential?

 

I just went with an inline head i am hoping that it runs just as good as the canted stuff with less valve train problems and better geomety hopefully it will be more reliable and make just as much power as a canted if not more. SBF But i got a really good Head guy Letting him figure out what will and will not make power for my application

Another screen name? Really?

 

BEC was talking about a canted head for a pontiac.

 

I run a splayed head with a cast intake and also have a sheet metal two carb set up. . Inline heads work better in a cast deal.(one carb..) But if you can run two carbs and a sheet metal. Canted is itfor sure

 

SB2's are canted and work just dandy with a cast intake. That is what they were designed for.

 

most progressive canted designs will allow a larger valve and commensurate flow numbers with having a SMALL chamber.
this allows a smaller dome to achieve the higher compressing for a N/A setup.
it is generally agreed that the smaller dome/chamber will allow a cleaner / undisturbed burn path and so the chance of detionation or dead spots is obscure, even with the relatively high compression ratio.

 

X2 imho,I looked at it like when engines are more bore limited the canted valve would allow a bigger valve for the same bore size and according to theory would move more air because of the valve size. Is that correct in reality? More times then not it is,will your car always go faster-accelerate better with a canted valve headed engine NO. So there is a lot to this question that cannot be answered without a ton of information and a lot of experence with that combo. In LIberty Dan
