  • is steam engine in disguise :p

  • hmm maybe at a guess he is making the head lighter whilst thus and therefore removing the aluminium material via a rotary cutting tool thus enabling lightness and such like?

  • sounds like; fap fap fap fap fap fap fap fap

  • I get in that position sometimes, where your putting in seats in all the "holes" and then decide to make it breath a little better by removing the shroud around the exhaust valve

  • Looks like a chamber sweep cut to the bore edge. Has a funnel affect on the exhaust, as the valve opens under pressure. Valve opens as piston is coming up, "funneling" gas threw the seat.

  • Looks to me like someone picked a seat cutter that was WAY too big.

    LOL

  • is this the first stage of fitting larger seats for new bigger valves or are you altering compression ratio??
