Oil return tubes with long stroke engines

[Wally]

Oliver,
Thanks, your expertise comes from experience also, I notice from your answers: this is the best. One question though: The reason I chose the 5,7 '' rod is that even with this length, the original rod length/stroke ratio is higher ! It seems strange that approaching the original rod ratio would give such a different engine characteristic. Furthermore, I hoped to reduce side stress in the cylinder walls by the longer rod and so also reduce heat build-up.
What are your feelings on that matter?

I'am very axious to hear from the latest head developments. keep me/us posted! Looks very promising.

Could you also please comment on my question for the longer pushrod tubes?
