Having a 2056 built for my 75 914, Anything I should consider? Options

[TRP]

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

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

I spoke with Jake about my desire to keep the L Jet and the 9590 is what he suggested. I had considered the 2.0 heads, but that would lead to needing new exhaust and new intake runners etc.

I could consider sone heads from the guy down south who does magic with 914 heads. I'm assuming Im leaving some HP on the table, however I'm undecided on which way to go there because of the Ljet. Ken can work some magic on my 1.8 heads and get some of that back, if you all think it's worth it. I know the 2.0 heads have the spark plugs are in a more optimal place, but again... requires new tins, etc.

What am I leaving on the table with the 1.8 heads? Keeping in mind the LJet and 9590 cam?

Thanks!
