Perhaps a fellow forum member could drop by and give a listen.
Location?

35K is waaaaaaaaaaaaaay too early for a valve job and timing chain.
Unnecessary parts, repairs, and charges. Did the "old" parts get saved?

Pull the vette outta that shop(and harm's way).

You're getting raped. Find an actual mechanic.

No way should your car need a valve job,unless it was not mantained.Check the vibration dampner it may be loose??

like others, i am very uncomfortable with the repairs which were deemed ''necessary'' for such a low mileage vehicle,tho

Aside from

the mechanic, who may or may not be competent the above suggestion is the only one I have seen that presents a plausible cause. I am neither defending, nor accusing the mechanic, but trying to redirect this back to a problem/solution needed thread, with no offense to anyone. With a new valve job, meaning new head gasket Redrose's comments certainly seem plausible, almost likely.
Any others?

Have YOU personally seen/listened/driven the car since these"repairs" were completed ? Has anyone run compression test/pulled valve cover(s) and inspect valvetrain since then ? Had one that baffled us,slight miss when warm,slight tapping noise,compression down about 15 psi(use a high quality,accurate gauge and test all cylinders identically) Upon removing Dr side head,we found #1 piston NOT coming up to TDC,about 1/4 inch below deck ! Pulled engine,#1 rod BENT,piston skirt/pin boss rubbing(knocking) on crank counterweight ! Guessing it got some coolant in one cyl from previous(and poorly done) intake gasket replacement,cylinder hydraulic slightly and off she went ! I second/third other suggestions to politely remove your car from current facility and perhaps explore a different "mechanic" maybe a local forum member could suggest/direct you ! PM me if you would like me to email you a pic,I kept the BENT rod/damaged piston as a souvenier
