Aluminum vs Iron compression on pump gas

Mad Dart I'm curious as to why your switching to magnum style valve train? LA head rocker shaft system is superior IMO. Do you plan on running a girdle on the rockers? That's going to be quite alot of stress on a 5/16" rocker stud.

Fishy,

Also if I was to do it all over again I would have stayed with the LA style edelbrock heads. There was an extra cost with the JOMAR GIRDLES,,,,,,to get everything to clear I had to get TALLER valve covers and it will certainly take away from the STOCK appearance. I was going to make an adapter for the heads and run the LA valve covers........just to be incogneto but cant do it now............there is just too much room that is needed.
