Before I build it - Thoughts on an 1883cc motor for my 356A

Registry Members
I’ve had the components for a modified 912 based motor in their original packaging awaiting a suitable donor car for almost 20 years!
You know how it is…………….. work, family and other projects always seem to take priority.
Early this year I acquired a matching numbers, RHD Aussie delivered 1959 356 A coupe. I guess you’d call it a barn find as it has been off the road since 1964.
It’s in remarkable condition, silver exterior with a green interior and has never been restored. It hasn’t fully escaped the ravages of time however and I have commenced a suitable sympathetic restoration
The plan is to store the recently rebuilt matching numbers “ A” motor and rebuilt matching number “A” gearbox and in their place transplant a 1883cc 912 based motor and Skirmants built 741 gearbox .
For added braking power 60mm Carrera front drums are also to be installed.
Before I assemble and install the 1883cc motor, given the length of time I’ve had the components and as technology marches on I’d like to ask registry members about their experiences with similar configured powerplants
I am on the right track?
Are these LN 1883cc motors reliable?
Are there any tips you can give me?
I am also planning to go twin plug and in doing so up the compression to 11.1. (Petrol here is 98 Octane).
Motor (Type 616 1883cc)
• 912 Crankcase Blueprinted back to standard and converted to Full Flow Oil by Competition Engineering
• Scat 74mm Billet light-weight knife edged crank
• Carrillo Rods
• LN Engineering 90mm B Nikasil Barrels with JE Pistons (10.5 Comp) .
• ARP Head Studs
• 912 Cylinder Heads modified by Vic Skirmants. Includes: Porting heads, manifolds, combustion chamber re-contouring, 8 new race valve guides, 4 new Datsun style 40 mm intake valves, 16 new Datsun valve spring keepers, 4 new 34 mm with 8 mm stem exhaust valves, 8 new racing valve springs, 8 new Titanium valve spring retainers, 8 new valve lash caps, Valve spring shims as required,
• Dual 44mm Webers, Manifolds, Air Cleaners and Crossbar Linkage
• Elgin Camshaft – Grind 7208 – 19
BAS Stainless Steel 4 into 1 Sebring Exhaust
• 912 Rocker Assembly – Short Exhaust Rockers Ground and Shot Peened by Vic Skirmants
• Chrome Moly pushrods
• New 200mm flywheel lighten to 14Lbs
• Alum oil cooler
• Vic Skirmants Oil Pump Cover with Oil Line Outlet and Relief Valve
• Remote Oil Filter Adapter
• Alloy Finned Oil Sump Cover
• Old Skool 912 Alloy Finned Rocker Covers
Any feedback is greatly appreciated.
Cheers
