la/mag cam info

trying to gain some knowledge

acquired a TBI roller cam 360 la

will a magnum cam fit or somewhere I had seen a mention that the lifter bores are different? along with the fuel pump eccentric deleted ...

Besides a regind on my current cam are there other options and what is the durability/max out of spring pressures and lift on the factory roller lifters ? Motor had 87.000 miles on it prior to pulling it and it looks clean inside...
