    IS Head: Valve size @ 86mm

    What valves are you guys putting in these heads? Will I be able to fit +1mm intake & exhaust like I want to or only intake? Can you fit larger seats or should I try to recut stock seats +1mm? Will they fit in the same place or how much do they need sinking in?

    What motor do you use the bigger valves from?

    If I need to sink the seats into the head should I run a regrind cam & thicker spring seats to offset the difference and workaround needing lash caps?

    Thanks for any help - I'm pretty new to the M20B25 & 27
