Installing a V8 into my car (finally!) and need gaskets for the intake manifold and the exhaust headers.

Before I just get whatever the auto parts store has, I was wondering if there was anything better than that.

I need intake & exhaust gaskets. Intake is an Edelbrock Performer so don't believe I need the crossover port.

I've seen some interesting exhaust gaskets, some even made of aluminum... I really have no idea what to choose!

So, ideas?

 

Get the proper intake gaskets to match both int. port and cylinder head port. Check OE gaskets they are thicker to give proper crush. Don't use the standard Fel-Pro blue thin gaskets (vacuum leaks and oil consumption). On the headers make sure flanges are straight and flat (no weld beads sticking up, file them down). I always use the gold or orange High Temp RTV sealer only no gaskets. Put a bead of sealer around port opening only (don't put around any bolt holes) follow directions on sealer tube. Retorque bolts after heat clycles. Allow sealer to cure properly. Have had headers on different vehicles sealed this way for over ten years with no leaks. Also use on flat collector gaskets.

Remflex gaskets are THE sh*t:

Super THICK. These things never leak on us.

i grabbed a set of copper exhaust gaskets off ebay and theyre awesome

 

Thanks for the replies!

So go with OEM gaskets and not the thin paper kind? Can do.

Interesting about not using exhaust gaskets with headers, I haven't heard that method before. Very cool idea.

Cool, I'll look into those! Man they have a lot to choose from for the SBC... which did you go with? http://catalog.remflex.com/category_...how=100&page=1

Like these? http://www.ebay.com/itm/131533011118

Though not sure if I need round or square holes. Haven't pulled the intake off yet.

 

You have to measure your exhaust tubing at the flange and decide on round or square. There may be differences year to year so I wouldn't rely on what anyone else used.

Makes sense. I'll measure my headers.

As for intake, looks like these are the most common sold on ebay. They OK?

I used the Remflex for my install too. Very thick, no leaks. ...of course I shouldn't have had leaks regardless of which gaskets I used. ....Are they better? I dunno. Did they work as intended? -Yes.
