as title says i have a spare Gt3 head.
its been skimmed & pressure tested.
also had new valve seals fitted at same time as i had a set spare.
also a stud snapped so i had it helicoiled with an insert for strength.
there is a crack between 2 of the valves that are hardly noticeable.
o yeah & gave it a bit of a clean.
