    When i install my MSD setup, it will be limited on the rev side @ around 4800-5000 rpm. There were no valve float with current unkown springs.

    How can we help you get "KNOWN" springs for your project? Surely there must be a way.

    Would if help if a 'cousin' currently living in the USA sent them to you? What do you think, Cousin (fill in your name)??

    Was trying to find some info about the head i purchased from ebay, but unfortunately the history goes as far as 2017 :D

    Well, let us see what becomes of this combo, at this point there is so poor weather outside already (road testing made impossible), that there is no hurry for my mechanic to finish the product with what we got until spring arrives. If it ever will :D

    Funny that You mentioned the cousin theme, i actually have at this point one cousin (albeit twice removed) living in Florida. Seasonally, though, since hi is supporting his sons efforts of graduating univeristy in US.
