Talon vs Pioneer Cylinder Head Question

[SLOWPOKE693]

Are these identical parts or different in some way? I stumbled upon a used Pioneer 1000 bare cylinder head that I can pick up cheap. I'm trying to piece together a motor build for my race car and would love to have a cylinder head pre ported and ready to bolt on so I can continue racing while it's being worked on.

Anybody know for sure either way?

Their different (HL6 part number for the Talon head) but i couldnt tell you why. Ive never had the chance to set them side by side and see.

It appears the valve guides are the same, Exhuast valves are Talon and 1000 Africa Twin only. Head gasket is Talon only, so is the head cover.

Maybe the larger throttle bodies made the intake ports larger too?
