Compression ratio what to do??

I personally would go for a c/chamber Eddy head as he's at zero to raise CR and hp all in 1 go, cfm will help breathing/hp but ally needs more CR so full benefit won't necessarily be reached. X heads are the flavor so gotta work with what the OP has. I had plenty of torque with my set up, 3500 stall and later 4200, but he's 4 speed so no issue. But as I said what he has will work and make tyre shredding power/torque.
