I've been told the two can't be used together but I don't see why. I have a 3500 & 3400 lower side by side and after a few measurements I don't see any reason for it not to work. The only difference I can see is the little notch at the mouth of the 3500 lower. Enlighten me?

3400 lower on 3500 heads?
Increasingly I find the difference between a "fact" and an opinion is the number of people who believe it.

like Ben said, there is a big difference in the orientation and shape of the ports. Not going to work at all.

Alright, thanks. So even if I smear a bunch of jb weld on it I can't make it work? JK.Increasingly I find the difference between a "fact" and an opinion is the number of people who believe it.

And this whole time I've been using cheetah blood?sigpic"It's your car. Do with it what you wish, but as you enter this unknown world you will need to invent the wheel all over again. For the adventurous and those that are backyard mechanics who have nothing but time you might like this. Most have plenty of frustrating moments and the process usually takes significantly longer then what anyone could imagine. The end result of this conversion is completely up to you." - Jon McCullough of BMCautos.com
