As the title states, I'm having Ken Jansen build me a 2056 for my current 1.8l powered 914. I plan on keeping the LJet and 1.8 heat exchanger / Bursch exhaust system.

We are starting with a 1.8 block and 1.8 heads (I purchased a 1.8 core) locally. Ken will be providing a 2.0 std/std crank and all of the required bearings and gaskets/seals.

I have already purchased:
- Raby 9590 Deluxe Cam (with Cam Gear, new lifters, pushrod, heavy duty rocker shafts, springs, and 911 valve adjustment feet.)
- 1.7 OEM Rocker Arms
- OEM oil cooler
- 30mm Full flow oil pump & Full flow (purchased from Raby)
- ARP Case Studs
- ARP Head Studs
- JE Forged 96mm Pistons and cylinders
- Matched set OEM std 2.0 Rods
- Oil galley threaded plugs
- GoWesty Throttle body
- Setrab Series 6, 25 row oil cooler with fan pack and thermostat
- New OEM clutch pressure plate and friction disc
- Advanced 123 Distributor for LJet EFI

Ken will be balancing the complete rotating assembly, including flywheel and pressure plate. He will also rebuilt the 1.8 heads, most likely going with 2.0 sized valves, May go slightly larger to match Jake's suggested valve sizes (Ken isn't sure about the necessity, I personally think we should.) We are cleaning the oil gallies and tapping the plug holes. Shooting for 8.5:1 compression ratio.

Anything else I should consider?

Thanks,
Ted
