Bigger valves in 24 valve head.

[ccoxva]

Is anybody running a set of bigger valves in there 24 valve head. If so does anyone know what they come standard in ? Just guessing that no one makes any that I've heard of?? Thanx.

Thought this was a pretty simple question?:bang

There isn't much gain, unless you make the bore larger. You end up with cylinder blocking the flow.

Thanks for the reply. The guys truck dynoed at 745 and he thinks thats his restriction.?

The stock head is the restriction...port and polish it the intake and exhaust and cut the intake manifold off. Put on an aftermarket intake. The valves aren't the restive part of the head...
