[QUOTE=FAD2BLK93;16429881]On a motor with this many heat cycles on it you REALLY REALLY run the risk of snapping the bolts off inside the head. Which is not uncommon, then u will be posting another thread on how to do the teardown and fix...i will be watching for it. Good luck.[/QUO
Thanks. Yes well Im probably going to hit the bolts with some WD-40 or any other cleaner/penetrator that can help loosen up some dirt and hopefully the bolts. Il let it sits for quite a while soaked on WD before I decide to untrue them, fingers crossed cause this is my DD =).

Stock gaskets are steal. Come to think of it, it may be a good idea to use a paper/steal core gasket. Reason being is a paper gasket is used mostly for surfaces that are known to be uneven. Stock manifolds have a true surface that mates to the head therefore steal gaskets will have no problem sealing. IIRC LT4 exhaust manifolds used no gaskets? Since the manifolds are this old, they may not be even anymore, which may have caused your blowout. IMO I think you should try a Fel-Pro 1406 or equivalent paper/steal core gasket. ARP bolts work well.

It's not really a matter of being "beefier" but more along the lines of widening the margin for error with surface area imperfections. If you blow the fel-pros out either the exhaust bolts came loose or a manifold is warped.

Btw I bought the stock original bolts, theres 9 in total I would have to replace correct? As well some PB Blaster =).
