have had success with the 1911 at no more than 8.5 on L Jet. requires FI tuning to get AFR correct.
the 1.7 responds well to increase in compression to 8.5 when combined with the SSI or 2.0 HEs and a Bursch type 4-2-2-1 tuned collector
the 1.7 HE has small ID pipe
if you are bold you can match port the exhaust a little. 1.7 heads have small ports and valves, thats why they run forever

Hell. Yeh I'd rather have 15/30 less horshpower
An last forever the have a failure rate of over 90% w.2.0 heads
Lack of bore spacing and aircooled do not go together

I always use 91octane if I need more pep
