so I have a 96 cherokee with, what I assume, is the 0630 head casting...I have a motor from a 93 with the 7120 head and I plan on porting the 7120 and swapping LS1 valves...but only if the 7120 head will work in place of the 0630 head. I know that the 0630 had dowel holes drilled but other than that will the 7120 bolt on the block without any problems? also this motor will be forced induction if that changes any answers
