KL3 head on a L4 ( or E series) body?

I know that I can run a KL1 on my L4 body, but what about running a KL3 on that same body? And yeah, I have seen the "Step Up" adapters on Ebay (from lighthound), that allow you to do this conversion. Ok, now to the question(s) at hand....

Are there any concerns with heat when using a KL3 (plus the adapter) on my L4 body? Will I fry this head by using the small L4 body? Or am I just being overly paranoid?

Obtw, I did a search and came up with zip, zero, nada. I'm sure that this was answered on the old board, but I'm just not finding it over on this new one.. If anyone has a link, please feel free to post it.

Any advice is appreciated. I feel like such a newb.

It should be fine, I had no problems using a KL5 head on the L4 body.

Thanks for the info!

I like that look!
