Head gasket question I keep hearing about cometic head gaskets, are they the best ? Are they MLS ? Do they come in different thicknesses and do they have a small bore size for the 4.8/5.3L ? Are they about the same prices as Fel-Pro ? I’m looking for a good set with the smallest cc I can do and get proper quench clearance. I gotta wait till after build to confirm piston deck heights. I’m doing a TRUE Blueprint Rebuild on a mild torque engine 420-450 torque/HP build.

I’ve been out of rebuilding engines for 2 decades but it’s interesting that you say Fel-Pro junk as back then they were the go to heads gaskets including intake, valve cover and header exhaust gaskets. Especially when looking for larger port sizes. What’s now the best? Especially if looking for performance intake (cathedral ports) and header gaskets?

slightly bigger than stock, 706 heads, porting/ port matching intake n exhaust ( yes I know intake on head side slightly bigger while headers need to be slightly bigger than exhaust port side)
