Cam advice for ill advised 318 combo?

moper said

MP thin head gaskets, the Summit "small" camshaft, cheapie small tube headers. If you want a little more romp the Comp Magnum 270S would be fun.

I did find the Magnum 270S on Comp's website,A couple questions..
1) do you think this cam is OK with my low compression?
2) why do you recommend a solid lifter cam over a hydraulic?

I'm hip with the solid as I have a 273 in my '66 Cuda and have had too many Slant 6 cars to count, just curious the reason you chose it over the 270H ?

Depending on the response I get to this I will probably go with this cam.

Thanks again
