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
