6.2 mercruiser valve springs?
 

I am fixing a blown head gasket on a 2002 6.2. Does anyone know cam specs or where I should source replacement springs? I plan to use MLS gaskets since this blown headgasket thing is somewhat common. Thanks!!

Are the springs broken? If not I don't see why you wouldn't reuse them.

The original 6.2 had some custom goodies. Aftermarket heads and forged crank . I believe something beyond the gm crate motor cam also. What are the part numbers on the heads?

There was no unicorn stuff on the 6.2s.

The heads are just GM Vortec. I did figure out that the cam is a crane 104224 from searching some forums..Everything looks good I just figured 15 yr old springs may be worn and weak. Any head gasket recommendations??

i would want to find out why the head gasket went bad.it can,t be to bad if it lasted 15 years.i would check the block&head for warpage.

See if there's a compatible beehive spring. They are lighter and can handle more rpms with lower pressures which equates to longer valve train life. Next item after that is short travel lifters. They act better at high rpm than the stock ones.
Use whatever stainless head gasket gets you the right compression ratio while trying for good quench. Do those engines still use round dish pistons?. If they have d dish measure how far down from the deck the pistons stop then calculate what thickness gasket will get you the right compression ratio. If it all works out,get a gasket for .040 quench height, It's the distance from the flat of the piston to the flat of the head. Cometic and Felpro are good head gaskets. MLS, multi layer steel, or shim stainless steel work.

the op got 15 years from the stock head gaskets,the valve springs have not yet been checked,the op just wants to replace them due to their age ,imo their is no need for beehive springs or mls gaskets.installing mls gaskets to surfaces that have not been prepped for them can lead to early failure.as i stated earlier,the op needs to find the root of the problem[blown head gasket].after all it is just a stock 6.2 that has made it 15 years with the factory components. the op could add the things you mentioned but will see no performance gain and i doubt any of those upgrades will last longer than 15 years.

I would just use the valve springs that Crane recommends to go with the cam

I would use some SS core Felpro Marine head gaskets that match the application.

Agree with the above. I operate on the assumption that surfaces are checked or corrected. But I still stand by beehives IF springs are needed. For the few dollars more they work better due to lower weight and rates to control the same amount of valve train pieces. Nothing wrong with normal springs though.
