Following with keen interest mate, a lot of people back in day chucked these motors in favour of an engine swap but I think they are so underrated. So reliable and love to rev all day long! Keen to see the power with the supercharger setup!!!!
Did you use the same valve springs? I'm assembling the same head but modified to fit my Fiat 850 [903cc] with an AMR500 and I reckon stiffer valve springs will aid with the rpm.
Love the build, I have been following it since the start and it is nice to see it coming together. Did you ever get a chance to post that rebuild caddy to thingiverse yet? I did have a look and couldn't find it.
