Advise needed

[smallv6]

I am starting a frame up restoration on my 87 GN, the car has only
64,000 miles but has seen some NY winters thanks to the previous owner. My question is should I do anything to the motor besides the obvious cleaning, hose replacement stuff. The engine and tranny are mint no problems with either, runs really strong.
Just would like to know if I should replace valve springs, sensors etc. Any advise would be appreciated.
Thanks all!

Well, if I were pulling the motor I'd change valve springs, valve cover gaskets, rear main seal, oil pan gasket, timing set and front cover seal, install a 160 F thermostat in a billet SS housing with a new o-ring, check the exhaust manifolds and crossover for cracks/leaks and repair if needed, change to new, larger injectors, and probably some other stuff I'm forgetting, but I'm sure others will chime in...

If the engine is coming out anyway, do the timing chain, oil pump screen, at least plastigage the rod and main journals, valve seals, have a good machine shop check the valve guides and seats, injectors and pressure regulator. the only sensors i would automatically replace are the coolant temp and 02.
