250- integrated or non-integrated head? Quick opinions needed...

[Grimm76]

Well, i am about to pull the trigger on a gently used 250 six through a yard in Vancouver- he tells me that it will take a day or so to get there. Should I ask for a non-integrated head or replace what was in there? I believe that the non-integrated head (separate intake from head, right?) needs some kind of plumbing to heat the intake- does that usually come with or would I need to scrounge some more parts? I will be asking the guy at the yard the same questions, just wanted some more experienced opinions.

I have seen/read enough about these motors that I will appreciate the 'old school' factor and once it is clean and painted up, it will be cool.

Opinions are welcome and appreciated
thx
