Can I remove the heads to change the head gasket with the motor in the car? Should I just do 1 or both heads? 1995 z28 with 383 in it THANKS!!

 

Yes you can do it with the motor in. I would do a test to make sure the other side isn't losing compression and if not then I would only do one as long as you are using the same gasket

 

Can aynyone walk me through how to pull the heads while engine is in the car? I am thinking maybe I should do both while I'm at it. Just a question here: Has anyone ever used therma gasket or steel seal?

 

I'd go ahead and do both sides while you are in there. I mean you already have the intake off and everything. The kit you get will probably come with both head gaskets anyways.

 

What is the BEST head gasket?

 

OEM from GM.

 

Hey RamAir: Do you have any answers to my above questions

 

Drain the coolant from the block and radiator. Unbolt the accessories and brackets from the block/heads. Remove the air pump and coil / icm. Remove the intake manifold. Remove the valve covers, rocker arms and pushrods making sure you organize them in a manner which will allow you to reinstall them in the same spot they were removed from. Remove the exhaust manifolds. Disconnect the ground connections on the back of the heads. Unbolt the heads following the proper sequence and lift off.

It's easier said then done but that'll get you started in the right direction.

 

The best gasket Is either felpro or MLS gaskets but those are more for people with porting done on their heads as it can be a custom made gasket set. Its a really thick gasket but it works.

 

guess i shouldnt have bought my daughter this car, had no idea how much power it had until after i bought it. Now she's in love with it. ARRRGH! Should probably replace 383 with 350 but hate to spend so much on another motor

 

Sure you could find someone to sway you their stock 350 + some cash for your 383.

 

I would sooner use a junkyard engine than a budget rebuild or "budget performance" engine. If it is having head gasket troubles that should tell you the work is questionable, probably all of the work.
