    I'd be worried it's too big and will alter the velocity of the air.

    Shiney though

    Shame it does't look like that any more

    The face of the head has been attacked with a carbide burr to see the damaged/weather it can be repaired and welded, its worse than the picture as the valve snapped off and rattled round the bore before making its home in the head face.

    Thats just the start of the damage been done and only some of the valve that have been bent/snapped/damaged

    It can be repaired

    I've repaired heads MUCH worse that yours

    I repaired a RS2000 16v maxi rally car head last year that has major det problem and had a mashed up compression chamber. With a little CNC work and my handy work its now up and running pumping out 255bhp N/A power

    Wrong length bolt fitted to the crank timing pulley, engine was cranked over, the bolt got jammed shocking the engine to a sudden stop making the timing belt jump bending/snapping loads of valves, damaged the combustion chamber, valve guides, pistons and gazz's pride

    leave engine building to those who know what they are doing...

    think you are saving yourself money "having a go" yourself........... Beware

    It costs you far more in the end

    surely once you have assembled the engine, you would notice something "catching" when you turn the engine over by hand.

    I now know why its smokes, Its was nothing to do with the oil seals, gazz said it was more white smoke with a hint of blue?

    Well the head was warped so there was leakage between all cylinders, it needed a few passes to get the head flat and true.

    Happened since gazz fitted it, looks like it over heated at some point. Maybe during bleeding of the rad?

    Every head i do gets a skim unless i'm told not to but alway advice to get it done.

    It was skimmed, Every time i had your head it was skimmed.

    The marks in the head was corrosion and nothing to do with the firing ring, Yours was warped across the cylinders causing leaks between the cylinders. The machine doest lie and you can see it when been skimmed.
