Starting the rebuild of a 78 200 to go in my 61 Falcon, got the motor torn down and ready to take the head to the machine shop. Goal for the motor is mild/better performance smooth cruiser that runs good on the interstate and around town & something the wife will enjoy driving. Planning on running the : CSC-264-HSP-12 264/264-112* Hydraulic Cam , using the 6 cyl handbook doing the 3 angle cut on the valves, backcut the intake valves, mill the head .050, also plan on running the CI header and there new 1bbl carb ,have a C4 auto trans and the DUI dist. kit. Now the questions, going to replace the guides, seats, & the valves, reading CI's site on the valve springs little unsure on which one, 302 valve with or without the dampner for the above cam? Next there site warns that you can cut into the water jacket when you go to the 1.460 Exhaust Valve but is not mentioned in the handbook, is this really a issue or just a CYA for the product? Plan on using the Non-Adjustable 1.5 Rocker Assembly, .530 Teal Viton Valve Seal , and the one piece retainers. Looking at the Dual Roller Timing Chain Set (170/200ci), any feedback , worth doing? Going to have the engine balanced and use one of the new single groove balancer. Have lots of experance with other inlines, Landcrusier's & Jeeps , Samurai 4cyl and the M151 Military jeep, just getting back to Fords and really like the inlines over the V8's any other suggestions or recommendations or tricks of the trade? Great site thanks for the help
