Started to prepare the cylinder head. This one's from the XR3i i bought eight years ago. The engine ran 160.000 km and was fine. It's a '87 spec engine, so the valve seats are fine with unleaded fuel. My lambda sensor don't like lead or any other kind of fuel additive.

Today I took off all studs so there's nothing in way for the tools.
And sure - have to take out valves also to do something to the ports.



Custom-made valve spring compressor. But works fine and was free.



I knew that the Irn Bru extreme value pack will be useful some day




The old cylinder head my mate modified six years ago. Will be some kind of an example for me to do the same to the XR3i head






Some kind of bad luck with the old head...




ATM there's a modified RS1600i cylinder head on top of my engine. But this didn't work as good as the old cylinder head and it's for leaded fuel so not really good for my lambda sensor. And exhaust valve on cylinder 2 isn't working properly so it's the right time to change it.
