Magnum Heads with LA Valve covers

LA valve cover gaskets all day long on Summit.

You can get anything from steel core silicone reusable ones to standard junk cork.

Just be sure to use some RTV on the holes that you skip and you'll be ok.

For what it's worth, I'm using these with some load spreaders on the bolts with stamped steel covers that are straight, that don't have sunken bolt holes.-

They are steel core, fiber/rubber composite, don't need or use placement tabs because of the steel core that keeps them from curving and they are nice and thick, so you get good cushion for variation and clearance for oddball intake manifold stuff. They do good on the ends where rubber and cork fail and hey, they're almost the price of a pair of cork ones from AutoZone.

Less than half the price of most steel core and aren't entirely rubber, so heat won't shrink the crap out of them and crack them like rubber ones.
