What are your expectations or goals? If the goal is to have a motor that can run okay with minimal work, could be fine.

If your looking for a high performance engine for possible future hp upgrades, its probably not worth it.

Here is my observation, 100% of the time....when a guy that really does not know much about engines/parts/machining, buys a completely rebuilt engine for a price that is too good to be true....it always is.

The one redeeming aspect is the 915 heads. You might be able to actually get 9:1 CR out of it, if the pistons arent .100" in the hole (like some are). I'm yet to see a guy that is on a budget do a set of factory heads correctly in the last 5 years as the cost is higher than new Stealths.
