Y.G.2:0 : Yes ,LA head gaskets work on Magnums.(same ,ignore push rod holes. Mr. Gasket p.n.1121 G, one per pack. Stock compressed head gaskets,. 050" compressed. A couple of tenths ,to be had.
I wanna pull the heads and have em looked over and ordered new locks retainers seals and springs from Hughes today. I could take .010 off the heads for a total of .030 off . That's close to full point I think. And it's super cheap to do. Thanks abodybomer ! You are always a big help
