So, i need new head gaskets ( i hope its the head gaskets ). anyways, what would you guys recommend to me to avoid any future problems? The block has been in the car for 3 years w/out moving and i just now got it running again and changed the oil and its all milky :( . Also, what is the stock bore size for a 92 350 Vortec ?

I want to say 96.01 mm

Just drained the coolant so i can take the intake off and its clean. I thought if a head gasket was bad both the coolant and the oil would look the same ? Maybe the coolant entered the oil some other way inbetween the 3 years of sitting ?

If I understand correctly, this motor was together, in the car, filled with coolant for 3 years, you started it and ran it, the changed oil?
You can have coolant in the oil, without vice versa. Change the head gaskets, replace with good ones, (FelPro, ROC) and FOLLOW THE MFG INSTUCTIONS! Sorry for the caps, but it makes a difference (which side up, torque instructions, retorquing, etc). Use sealer if recommended. Hopefully that will fix the problem. When you pull the heads, check the bores (not too obvious!) as you might have had some fluid leak into the bores and past the rings to the oilpan. Not likely since you started it. I'm not real familiar with 350's, but on BBC you need to put sealer on the head bolts, as they go into water jackets. That might be another source if SBC is the same.
Mortec sez except for '89-'95, "LT5", in "ZR1" Corvette 32-valve DOHC, all the 350's had 4" bore.

They didn't make vortec engines till 96. U just have centerbolt heads, right?

Did it run 3 years ago? Is it all stock? Rebuilt? Do U know any history of the engine?

When an engine sits for along ,the crankcase can develop condensation and make your oil look milky.Change your oil and test it out.Should be ok if there was no problem with engine before it went into storage!(speaking from expierence)

yeah, its got the center bolt valve covers. The engine was rebuilt at a vocational school. It was honed and has some sort of a cam in it, mostly just a stock rebuild though. It ran in a car for 500 miles, then got moved into my chevelle, it's always been a running motor. I've already got started on taking the intake manifold off and the headers, so i'll just go on ahead and make absolutely sure the head gaskets were done right.

I was thinking of using copper head gaskets but im lost when looking at the width differences and everything. I just need the best head gaskets available for a stock 350 bore.

You don't want copper. Depends on your pistons and cr.

Permatorque type gaskets are forgiving...........but may yield you a poor quench.

What type of pistons and head casting #'s do U have? Is it just a stock truck motor with 76cc heads and dish pistons? Has your block been decked?

You'd be surprised how much condensation can develop over a 3 year period. I've had deisel tractor fuel lines freeze up in the winter after one season of sitting, all from condensation build up in the tank.
