1000j / GPZ11B2 Cylinder head.

[zed1015]

Looking for a decent Z1000J or GPZ11 B2 head.
Have a Stock repaired 1100 Unitrack head or other Z parts to trade if required.
Uni head needs a valve and guide job.
Has helicoil on one plug and all the cam cap threads have been repaired with 30 mm deep steel inserts.
Only reason for not using the Uni head is the steeper exhaust angle doesn't match my Wiseco's.

You can mill the exhaust pockets on the Wiseco's to allow the Uni heads different exhaust valve angle to clear the pistons. Mine was done by Ray about ten years ago and has been no trouble since then even at 10,500 RPM!! Above that at 11,000 the rod stretch is 1mm and the pistons kiss the head but the valves are un-touched.

Yes! i was going to do that myself but decided against it in case i swap the head to another engine or re-bore at a later date.
All my motors are Early zeds and i can't be arsed to mill the pistons each time i do a rebuild.
This is for the turbo build and the uni head would be wasted on it anyway so just going for a J and port it out with bigger valves.
