164 24 valve engine.

Ok I will start the ball rolling with the following:

The 24v is coil on plug
The exhaust manifolds have different flanges
The ecu is different
plenum is different
i seem to think the engine mounts are different
the bigger heads might foul the back rail of your chassis

probably a few other differences as well.....

Corky (tipo 158) has a 164 spec 24 valve in his corse, maybe he could answer your question?

Unfortunately Steve your chassis was the last one to be built without the mods to allow easy fitment of the 24valve engines.
I think your biggest hurdle would be the rear cradle top crossrail which Neil mentioned above.
There is one out there but I lost touch with the guy who was building it and don't know what he had to do.
Last time I saw it the engine was in and sitting on the 12valve engine mounts I seem to remember, but there were issues to be resolved at the top end.
Corky rejigged his chassis and made new mounts I think.
