Difference in deck height on La and Magnum blocks

[hemichuck]

I was wondering if anyone knew how much difference there is in deck height between a La 360 and a magnum 360

I believe Magnum are 9.6", same as the LA motors. Now having said that the factory blocks are all over the place, it's something you need to have checked at the machine shop. My 90 block needed to be decked to get it to spec.

LA 9.599
Mag 9.585

not much...but both need to be checked..

Magnums tend to be machined closer to blueprinted specs. LAs can be really far off. Least that's what I've found.
