Spec advice for new motor build

So im finally coming to the end of my 3 year long project on my bug



and now need to consider the engine.

i have two donor motors - a 1700 type iv and 2 litre type iv - both died with valve issues.

I am thinking about building a 2056cc motor based around the 71mm crank. Eventually going EFI and turbo but on carbs to begin with. so heres my plan

CU Case acid cleaned and machined for porsche fan
Crank, pulley and 915 conversion flywheel dynamically balanced
Stock 2litre rods balanced and ARP bolts (however for a little more £ i probably could get a nice set of rods - thoughts on this?)
96mm Keith Black Pistons
considering using OG barrels bored out as i have read the OG barrels are made of better material?
Straight cut cam and crank gear
Cam choice im unsure on at the moment - opinions?
Stock lifters and push rods (although i have been recommended to sleeve the case and use uprated lifter. again opinions?)
Rockers?
Dry sump kit
CSP python exhaust

Heads. now i have a set of 1700, 1800 and 2000 (square port) heads. 1800 have the biggest valves but i was considering getting the square port heads reworked. what do you guys rekon?

Once turbo'd im looking for around the 170bhp mark so quite low on boost. i want the motor to be driveable/reliable rather than an all out race motor.

any opinons/help great appreciated
