    do oversize valves suit stk pistons?

    Are there any issues running ferrea oversize valves 1mm and 2mm with the stk pistons or do the reliefs in the piston need to be larger to?

    cheers..

    Trimming the eyebrows is necessary with 2mm.
    Probably a good idea on 1mm.

    The bigger valves don't do any good unless you can mill out the seats

    heard that more boost w/stock valve size was the ticket anyway

    yes the plastercine test confirmed it today so the pistons are coming out. the seats and head have been extensively machined for the bigger valves.
