Sm Blk heads

Any real world tests comparing LA heads to Magnum heads.
Despite what a lot say I have custom cam grinders tell me the LA heads are superior.
...your thoughts / experience?

My thoughts
I can see how a camgrinder wants to see as much of his lobes motion getting to the valve instad of getting lost in the shape of flexing valvetrain and thats where a shaftmount system realy shines. anyone that has been paying attention while installing rocker stud girdles on a smallblockchevy with any kind of springpreasure knows what im talking about(yeah i know they are available for magnums aswell but not nearly as comon)
The magnum chambers are supperior,ports are probably better aswell.
From a hotroding perspective there is not nearly as many intakemanifolds to chose from for a magnum and that is a limitation depending on what you are doing.
