The absolute biggest thing you can do to improve things is to ditch them strombergs and bolt on a good pair of SUs.

George seems to like the later bottom float HIF units... which are admittedly better in many respects.

I like the earlier side float HS carbs, which are more troublesome, but easier to deal with (in my opinion..)

On a similar note... is there an adhesive sealant that is appropriate for intake/exhaust manifolds? I've used stuff on other cars, but never on the combined gasket that the Volvos use. Something perhaps that could be used only around the intake ports?
