    Default Head Gasket Replacement

    Do I need to pull the block to replace a head gasket on a 1999 Suburban (350/ 5.7). Also, whats the price for a new head gasket and grinding the old head? Any help would be much appreciated. Thanks.

    You don't need to pull the block, unless it's warped too. You might consider pulling the hood and fenders though. I think the job will go much easier, and you will at least break even on time.
    When you hear hoofbeats, look for horses not zebras.

    no you dont need to pull the motor, a head gasket set with all the gaskets you will need will be about $150 and about $200 to have the head gone through and leak and crack checked and replace any bad valves

    you dont need to pull the block out, you might also want to check if anything is cracked like z71 said.

    If you can remove the grill up front it will go easy, just use some towels on the fenders or hello scratches.

    Removing body panels arent needed unless you are shorter or just use a solid step stool, but a word of advise be careful with your back when leaning over when you actually pull the head off the block, they arent light, I strained my back once doing it. My local shop that does testing for cracks and warping charges $60 a head and 35 for planing if they are warped, also if you are gonna do one take the time and investment to do the other at the same time.

    do both heads.. vncj96 speaks the truth this is your truck not just a pay check from a cheap customer depending on the mileage a valve job is a nice touch.super high mileage motors have been rumored to break rings with freshened comp. but i've never seen it and a good straight edge with a feeler guage will check the block
