I know there was just a good thread on here about rocker stands.

I'm interested to find out whether ANY stand will bolt to ANY head, regardless of actual rockershaft positioning.

If I find a "deal" on a pair of heads, are there any heads that require unique and unobtainable stands ?

I'm just not hip on the stand interchangeability.

***********

So then, Part II:

If you get a set of rare and wonderful stands that re-position the shafts, for whatever reason :

Is it commonplace to need compatible rocker arms that are longer, or shorter, or unobtainable, or..........??

Are 95% of Hemis all interchangeable and only 5% rare/weird ?

I don't mean any billet / nitro / race stuff.
