What I can tell you is - no dogleg port....there wouldn't be much point in making a whole new cylinder head with this power-robber built in To the rest of those interested, please be patient

The problem with making cylinder heads, at what point do you decide to stop fixing OEM limitations in the name of keeping common with the aftermarket parts
I'll be interested to see what comes out. |

True, next you'd need a custom intake and exhaust manifold to make new port shapes that don't align with oem manifolds. |

You ignore the OEM stuff, build them correctly and tell people if you want them to work you need to do x. Im seriously wanting a set and the moment they got mentioned I knew it ment at the least new headers and very likely an intake manifold. Zero hesitation!!!

No matter the exhaust port shape or orientation, the limitation of both heads being so far apart will still be. I'm curious how efficient four oval or round ports (if that's how it goes) would be when they have to still merge, and how they would be integrated into the under engine area. What kind of crazy header design would it require?

At some point you have to stop calling it a Subaru engine. If you really want to get a flat 4 to make power you need to man up and change the firing order. That alone will net large gains in efficiency on the intake and exhaust side. Debating over a 'dog-leg' gains/losses where a pressure pulse hasn't even formed a front yet is arguable at best as there has already been testing that shows the flow from the exhaust/intake ports is negligibly different once a decent manifold and intake manifold is in place.

1) Straighten up the exhaust ports - custom headers - custom subframe - should be ok leaving the steering rack unmoved 2.) Custom intake port - new intake manifold or simply TGV adapters, but then are you just moving the choke point. 3.) Decided to correct the valve geometry/angles - custom timing belt and gears - new valvetrain - custom pistons If you really wanted to get some valvetrain gains, switch to finger followers, so that you can get more negative on the cam grind. Oh yeah, custom cams Then again, if you're running billet heads, your probably already on a billet block, so what's another $20k? Quote:
Likewise, I think the dogleg is drastically over dramatized. |

No, the firing order is a physical trait of the engine. To change it you have to change the crank and the cams as those decide which part of the cycle each cylinder is in relative to each other.
