    So, it seems my truck, 2004 5.3L Tahoe, has the infamous cracked Castech cylinder head problem on the driver's side.

    I've decided to replace the cylinder heads with a new cast ing --- not remanufactured (don't want to inherit the same problem again).

    RockAuto has a new bare cylinder casting made by Enginetech for $237.79:

    I was also able to find this supposed reinforced/strengthened version here for $345:

    Does anyone have a recommended vendor for new cylinder heads? Preferably, one which has an improved design like shown in that second link.


    Thanks guys!
