Hi!

I have a HEMI that was completely rebuilt but that was a few years ago....like 4....and its been sitting since...

I have turned it by hand every now and then, but probably not as often as I should have....

Its got a solid roller cam (mild under 600 lift).

I am worried that the springs might have gone bad, so I want to take em off to test them....but for doing that I need to take off the heads...

I was wondering if I take off the heads to inspect,,,,will I be able to reuse those head gaskets???

The engine has never been fired, but the heads were torqued to spec....

I dont know if it makes any difference, but its got head studs.

I think you are worrying too much...I bet it would be 100% fine..

If you want to put your mind at rest, air up a few cylinders and pull a few springs and check them out. There are tools designed to remove hemi valve springs without unloading the head studs. I wouldn't take the heads off. That's just me.

Was thins motor sealed up good? Id be more concerned with a mouse making a nest in there if the motor wasnt sealed off well.

Yes, it was sealed up good. With duct tape on the ports....and with plugs installed. INtake also taped.

I dont have the tool to remove the springs without taking the heads out....

So, will the head gasket be unseable if I take a head off???? Like I said, the engine has never been fired.

What kind of head gaskets?
Has it ever been started and been warmed up?
IF you have never started it and the springs have never been heat cycled, then I would not worry about them.

Head gaskets are composite, not steel.

Composite gaskets usually will leave some material on the head or deck surface due to compression from the heads being torqued on. If it were the steel gaskets then I wouldn't worry about it.

You worry too much. Run the doggone engine. Or if it is going to sit for longer, pull the rocker assemblies. But for a decent spring sitting for a decade shouldn't make a difference. No fatigue cycles.

i asked the guy at cometic and he said that if the engine hasn't been started, you are fine to reuse them. i would assume that goes for any head gasket.

i have seen threads on here where people are talking about reusing gaskets that have been run, and many people have said that works as well.

sounds like you are good to go

I would only reuse a mls or copper gasket and I would NOT reuse a composite head gasket EVER.

Why chance it? I'd back off the rockers until you're ready to use it.
