Is it worth the $ to build a 5.9 Magnum (or LA 360) without making it a stroker?

I’m not up on W2 heads but I didnt know they oil through the pushrods. Do They make oil through solid roller lifters?

Would it then be better to use a magnum block?

If you are using LA heads with a roller cam then use a pre magnum 88-92 roller cam block.
