Patrick, I was hoping you'd stop by. Your LA knowledge is A-1!

I was hoping that a head swap would get close to quench but apparently not.

Yeah, I anticipate my engine is a roller block with flatcam. I was under the belief that the Magnum roller parts were different from LA, though. Isn't the block's lifter bore taller or shorter between Mag and LA?

Although this conversion isn't that difficult, sometimes I think makes more sense to swap in the whole Magnum engine. If I stumble across a good one that's what will happen!
