77 motorhome 440 vs 71 360-what to use???

ya'll are great! Bmsjax, we're only about 35mins apart ever been on that website socalcarculture.com? They have a list of shows in our area it's great! I appreciate all the input very much....i've been gathering quite a bit of information on the 360 i have (both motors are complete from intake to pan) and it seems like a decent setup with a performer rpm, 2.02 heads, a nice cam, and a 750 i should be close to 350hp. The thing is though is that it is a "J" head motor, meaning by the time i have valves put in and machine work done, i might as well spend some more to buy the RHS heads. With the MH 440 heads, i don't know the specs but is there any performance in this head (new valves+pistons=power potential?) Thanks again, you guys have been wonderful:mrgreen:
