Do Weber carbs require high compression or is 9.6ish OK? Will Webers perform OK with a solid lifter hipo reproduction cam?

Compression doesn't really matter.

Any IR system does better with a wide LSA, at least 112*. Less than that, and you tend to get a lot of reversion. That's what caused the "Weber Cloud".

So a K code cam with an LSA of 114 degrees is good to go then.

Yes. 114* is optimum for an IR system.

what are you trying to accomplish with the setup? Do you want something mild and tame or are you recreating the real deal?
