Modifications worth doing??

[Tugmaster]

I'm trying not to get ahead of things on my project. More just thinking out loud.
As I look thru the different catalogs I see a lot of different upgrades and modifications you can do. I'm sure some are well worth the time,money and effort and some aren't. You guys have way more experteese than I do. Here's the ones I'm wondering about:

Four bladed fan

Thermostat

Modern points

Oil pressure gauge

Isolation motor mounts.

And anything else I missed.

Thanks,
Todd
