Scream'n 318 ?

The thing is, I cant understand why you would want to drill a magnum block for head oiling holes anyways. I think early ones had the oiling holes already in them. Arent magnum heads superior to LA heads? I mean dont people put magnum heads on LA engines quite a bit?

Probably depends on what a fella ha son hand for heads and rocker gear. I wouldn't want Magnum heads, mostly because I have all LA rocker parts and pieces. But if I had a lot of Magnum parts around, I might think differently.

I also don't see many aftermarket Magnum heads. At least not as many as LA. So that likely factors in too since so many folks upgrade piecemeal style and plan for future upgrades.
