Said there's maybe 10-15 ft/lbs and 15-20 hp difference between the two. Obviously, my heads are the overall limiting factor.

I asked about the RAIV roller grind and he said he'd choose the 236/242 hands down over it. He also indicated that it's geared more towards iron d-ports that need more help on the exhaust.

425-450hp is a nice step up from what I had, but I think I'd be disappointed with the mellowness of the 230/236. I'd much rather change out a converter than a cam later, so I'm inclined to switch it up and go with the bigger cam on the 114.

I agree with the assessment that the larger 236 cam may want a bit more converter than what you have. I'd be inclined to try it first as converters are fairly easy to change later if you decide. Easier than a camshaft change.
If you do the 236 on a 114 LSA, it's going to idle pretty well for you and make enough vacuum. You might find that 13" Continental works well enough to idle fine and drive well around town. Might not be optimum at the track but how often do you plan to do that??.....

Maybe at that point do a custom converter of your choice and see how that compares.
