I would use the GM MLS 6.0 head gasket.

I agree 100%. The GM MLS gasket will be fine for that application.

do not use the felpro 1041. the bore size is way too large. even for a 6.0L bore of 4.00". you need to use the head gasket for the LS1 motor as your cylinder diameter hasn't changed (3.898). get the 2003 MLS gasket for a LS1, not a 6.0L.

Felpro 1041 Summit Racing (http://store.summitracing.com/partdetail.asp?part=FPP%2D1041&N=700+0&autoview=sku)

Bore = 4.135"
Compressed Thickness = .041"

4.135 - 3.898 = .237" open area

what can happen is carbon gets built up in this area and can cause detonation.

now, looking on mrgasket website, they have a MLS gasket thats 4.060" diameter with a compressed thickness of .054". 3143G (http://www.mr-gasket.com/ProductDetails.aspx?brandId=1&productID=6403420&majID=500&minID=5012&selection=&minselection=) it says for 98-00 LS1. i know there was something about a notch needed for the older blocks. i'll try to look into it more later.
