Will the higher compression ratio be an issue when mapping the link ecu because of the risk of knocking? Keeping in mind that the stock knocksensors will stay in the block.

If you know what you're doing then of course not, just don't aggressively ramp timing until you've past max torque. Even keep the timing values static till you see torque decay heavily.

And yes, have knock strategies in place with the factory knock sensors would be an advantage with your tune.

In terms of the copper spray, I can't see any negatives with using it.

As I said, I would be aiming for at least 9.5:1 on any engine I was building these days. The fuel, the injectors, the coils and the computers have improved massively in 30 years.

How about the celarance between pistons an valves? Is it a problem, when I reduce the hight of the cylinder head on a neo engine with variable valve timing?
