318 with big valved or 340/360 heads

The more I'm reading and learning on here (which is a lot) I'm getting the understanding that using 340/360 heads or any heads with 2.02/1.6 valves is too much for a 318.

Now I'm already planning on putting a set of LA-X heads with 2.02/1.6 onto a 318 (was originally building a 360) I will hopefully start building shortly. I have got the KB flat tops will help bring the comp up a bit but would people prefer to use something else or stick with these heads. Keeping in mind it isn't as easy to find parts down here in Australia.

At the same time, I'm planning on doing a quick rebuild on a 318 in my wagon and may have stumbled on a short motor and heads ported out and ready for big valves (2.02/1.6). I'm just planning a mild build with around 1HP per C.I. Long term I would love to bolt a turbo on to the side but probably a year or two away at best. What would you guys suggest I do here, use the heads with big valves or just get a set of 318 heads I have ported and go smaller valves?

Appreciate any help and advice.
