No valve seal smoke, yet, but I do get black smoke from a rich condition when starting the engine after the engine is thoroughly warmed up and we're doing lots of stop & start with changing skiers, etc. My only thought is to change both needle & seats in the Holley. Have you had any carb issues?
Did you have any trouble finding a replacement block? I understand these are 4-bolt main blocks and finding a MarkIV (old) performance block could be difficult and would be pricey.
All you need is a Electronic Ignition Converson Kit from Skidim for around$100, fairly simple, follow instructions and you may need a coil too.
