Does anyone make better header gaskets than the Fel-pro that I have now? I think if they were abit thicker Id have better sealing. I had to remove the gaskets and apply the copper high temp sealant. I'll have to keep re-tighting them as they have some blow-by. The sealant seems to be working for now.
Thanks...
Also, should I apply anything to the header bolts to keep them from galling, or would anything I use just burn right off. I swapped the SS bolts for regular hardened hex headed type.

I'm not sure about the big block stuff, but I have found that for my cleveland the Mr. G ultra seals are better than the Fel-pros. They fit better, and dont seem to blow out quite as easily.

I'd be tempted to try some of those solid metal gaskets. They come in either copper or aluminum. I've used them on the collectors with GREAT results!

My tow vehicle (4cyl ranger with a header) Dont laugh! gets run flat on the floor for a half tank of gas at a time. On a 4hr trip, it would usually cook the collector gasket... even the good ones. I bought a solid aluminum gasket at the parts store and have had zero problems since!

ps. I use a dolly to make it a little easier on the 84' 2.3L workhorse. It has a pinto 2bbl, synthetic oil in the engine/trans/rear, colder plugs, colder thermostat, custom 3-row radiator, MSD 6AL, header, 2.25" exhaust, 5speed, and 4.10 T-Loc. The engine is completely stock, and is quite the slug when loaded down.

I need a full sized truck... any 3/4 ton 2WD will do. Maybe one of these days...

To those of you contemplating a brand new Diesel or V10 just to occasionally pull a hotrod around, kiss my a$$ ...

Good Luck!

Gary,

On my 351W with World Product heads the only gaskets that I have been able to get to seal are the EARL'S Graphite gaskets. As far as anti sieze compounds on the bolts the most will not handle the temp, but will help a little in removal. About the only stuff I know that will take the heat is called "Silver Goop" and is very expensive. If someone you know works on aircraft engines or in a power plant they may be able to get you a little.
