Re: Hedders?
I've been racing for about 8 years. Never could find a gasket that would last. Several fellow racers and one ex-mechanic/dragracer/parts salesman told me to throw the gaskets away and use the gray hi-temp rigid silicone. Put a bead on it, then snug the bolts up until the silicone touches the heads, let it sit for a couple hours until it hardens up some. Then tighten up the bolts like you would normally. I've been doing this for the last 4 years with no problems. Haven't even lost any ET. Hope this helps.
