LA heads on a magnum block

And here is what he did. He got some hallow 454 chevy pushrods and they were to long so he put a washer under the rocker shaft on all the stands tighten them down and bent the washers to fit the contour of the rocker shaft, fired it up and he got oil up thru the pushrod. How long do yall think this will last?? It running now

My guess is he screwed up the rocker arm to valve stem tip geometry. If it's a real mild cam it may last a while, maybe. I sure wouldn't have done it. Let me guess, he's too cheap to spend $50-60 for the right pushrods? Or the Chevy guys told him it's ok to do it that way, just like they told him the blocks are the same
