Got some more pieces of the puzzle in place today. Managed to source a 69mm counterweighted crank locally, along with a set of stainless valves and cut to length push rods. Also found a nice set of Engle
#6002 HD single springs on thesamba. The plan is to use singles as I doubt that the bus is going to see extend periods up at 6.5k rpm. Found some titanium retainers as well, just not 100% whether I will pull the trigger on those. Waiting to hear back for postage costs. Would be good for valve-train weight though.
Did pull the trigger on some valve seat cutters, a must if I'm going to remove the guides, port the heads, fit new valves and do a nice 3 angle valve job. Quite looking forwards to working through this process. It's not something that I've done with VW heads before. I'm interested to see what I can achieve.
