Ok- thanks

The question is then - Can I use the 305 AFR's ? (special gaskets ?)

The reason I ask this basic question is most of the literature I have read says heads are not interchangeable.....However I notice the aftermarket (in Summit, Jegs, etc) never mentions this.

What about running a 5-Speed because it doesn't have the boss ? I'm going to run a TKO Tremec.

I guess now if the price is right (because its brand new) I may jump on it for a 540 instead of a 496 using a donor motor.

Thanks
