Average Safe Boost level for a LA eng

a standard production small block mopar only using 10 head bolts wit h a lot of boost the deck tends to move around,,same problem with the buick motors,,
if you plan on making any type of boost and plan to beat on it, you should look in to o -ringing the block with a reciever groove in the heads,, or use a gasket that has a good track record,,

a mopar performance block will have a more stable deck then a factory production block,,
