Dual Port Head Rockers

Post by Matt » Sat Jul 21, 2007 7:29 pm

Are Dual Port Head Rockers different? As the push rod on number 3-4 (piston) ton the exhaust side don't line up. Ie the push rod hits the head?

Thanks
Matty

Shouldnt be

Dual port heads arent much different to the normal ones, only that there is a divider in the exhaust port

The intake is different too, much better flow. I post up pics later but you can easily see the valves through where the intake mainfold bolts up.

The Valves are swaped to standard EA81... They are the same arrangement to the EA82.

Sorry matt, never compared mine with standard..
