I will probably be doing the head off idea, seems like its a bit smarter. I will need a headgasket and stud kit, I plan for 350 WHP range, I have a good machine shop in town and I will have them tell me what they can do for more performance, Light port and Polish, gasket match things like that. I dont want to shave the head because I want less compression for more boost.....I will let them handle the valve install as well as cams. I will reinstall the head and torque down according to FSM. retime by the FSM and That should be it, im hoping.
