Another big head
Mike dropped off two OHV heads with me on Sunday, one was a head a sort of rebuilt a year or so ago, but it failed, appears one of the valve stems came out? Never mind I shall look at that another time. But more interestingly was a semi ported 1159 head. Its got the inlet track ported but not as much as the old 1256 head I gave away to Craig in Somerset. It appears the chambers have been enlarged a small amount as well, but again no where not as much as the old 1256 head.
The exhaust is still factory spec (ruff and small). the valves are large and for once the bridges between the valves look intact. I shall be stripping this down cleaning it and re seating the valves, then its ready for a 1159 engine.
