hey Travis! i've got a '65 nova wagon w/ '70 250 and th350. currently running a '66 194 head. boosted my comp to around 10.3:1, and depending on exactly which chamber size yours is, should give you a little over 13:1. like Bruce said, you'd probably be better off milling the stock head. with the head swap i lost a bit of low-end torque but picked up significant power at higher rpm. think it may help a bit when i finally get the clifford intake and headers and holley 390 out of the garage and into the car. i'm just over the mountains in kent, and make trips to Leavenworth/Wenatchee fairly often, if ya ever wanna exchange thoughts/ideas. know some parts sources as well. good luck with the project!
