Reasons for -
- 31mm buckets, so big cams aren't a problem at all.
- Narrower valve angle, 22.5°.
- MUCH better inlet port.

Reasons against -
- Squish areas are located in four areas Vs the G head's two large ones. I haven't measured them as such but I'd say the F head has about the same total area anyway though. So with work they're probably just as good but it's more work to get right.
- Hard to alter the lobe centres WRT each other unless you build a very small slotted drive gear between the cams.
- The exhaust ports also need a lot of work to get right. Cyls #2 & #3 are not too bad, but #1 & #4 are angled and need more work than the middle two. I plan on using ovaled ports, this'll make the job of making all the ports the same much easier.
- People think you're barking mad! Smile
