I buy an 600 SCi that was stored 7 years with 50 hours on it!
inspect the cylinders and so with micro cam from inside and there are blank walls with absolut no sign of wear or rust!!
New oils,impeller and prelube without sparkplugs! Drain the gaslines,filters and pumps and fill new gas in! it starts after 3 seconds and idle pefect!
I have at moment not change the valvesprings,as some maschine builder say at a cars they would not do after 10 years standing!??

My headgaskets had already started burning through when Eddie tore them down. If that happens too long, you risk block (worst case) and/or head damage (still bad). The headgaskets on the 575 are/were inferior (mine were year 2002 with about 200 hours on them).
Eddie rebuilt heads, cometic head gaskets, roller cam, and tuned ecu's - already had smaller pulley. Those engines ran great when he finished them. 100mph 35' Fountain Lightinng (2002 side by side)

This is all good information and very much appreciated, so far it looks like there are no issues with the head gaskets, I am for sure going to change the Valve springs, sea pumps and all the regular maintenance items of course, I have a friend who's semi retired but a great engine mechanic and he's going to look at everything and get the boat running for this season and we're planning on doing the Chiller, roller cam, pulley re flash updates over the winter for next season ... it sounds like there a lot left to gain with these upgrades ...
Thanks and please feel free to keep any other suggestions or experiences coming ... Cheers and Happy boating

Mine were burnt through at 100hrs. Not completely burnt through, but looked like they were minutes away from failing, not hours. If I were going to go to the trouble of putting on valve springs, I would most certainly go ahead and pull the heads and replace the head gaskets.
Valve springs are most likely OK though. Heat and cycles are what kills springs, not being compressed, especially by a tiny little hyd flat tappet camshaft.
