Replaced Head Gasket and it blew after 3,000 miles. Part was from ENGNBLDR and I think a FELPRO. My block coolant holes could be bored out from corrosion, I've read that this can be cause gasket to blow. Does anyone make a higher quality gasket? All copper? Oem?

Get the OEM and don't worry about it. or do you want one where it is said it's as good as OEM and wonder???

Just what did you torque your head bolts to??

Myself I like to wonder it add excitement to life.

60lb-ft with new bolts, however I didn't re-tapp the block holes. Might not have gotten all torque to transfer. Stupid mistake.

I really doubt its from a faulty gasket, Millions of people use FelPro, anything can be defective but theyre not exactly a low quality gasket or anything....I would be looking more into another issue....WHAT made the first HG to blow in the first place? Coolant leak and made it overheat and blow? Did you make sure the head wasnt warped when you had the head off (assuming it overheated)? Which can cause any head gasket to blow easily since it doesnt have constant pressure on all spots. Has it overheated since it had the new HG put in? or any other related issues?

don't use a tap on head bolt holes, just cut a groove in an old head bolt, to clean out the junk.

Original Head Gasket wasn't blown, replaced it when I did timing chain and cover. Also had head decked and rebuilt. Truck only overheated once 3k later, and that was due to coolant loss into combustion chambers. Did test and it was leaking at #1 cylinder.
