You will have to put the slant onthe carb side of the chamber to clear the pistons if they are standard firecrater pistons. You can do this with a hand grinder. Yep 350 head gasket, No you dont have to alter the pushrods when you mill the head,,, Ive taken .200 off a 8043 head and never messed with the rocker stands, the adjusters can be adjusted enough to compensate. another option is to put shims under the rocker stands, exactly what you machined off the head,,,, I doubt you would need the shims, but you know you can do it,,,,, Break in,,,,, , before you fire it up,,, make sure you have oil pressure, and oil at the rockers before you fire it up,,,,, Follow the head toruqe instructions, set the valves at .019 for now,,, cause you will have to readjust them later. Once the engine is running,, warm it up, you have to get the guage up to run off the cold mark,,,, then shut it down pull off the valve cover, remove the rockers and retorque the head again, retorque the manifold, carb flange. Do this while its warm, it makes a difference,,,, if the rocker tips are grooved, smooth em out. grooved will only make the lash adjustment harder to set. Now put the rockers back on and fire it back up, warm it up once more, and then set the valve lash to .017 hot. Run it for about 1/2 hour at half throttle,, after that, change the oil. Now, you need to put a load on the engine for a while, these engine wont break in and run right until they get about 10 working hours on em,,,, keep checking bolt torques and lash adjustments on the valves, if you can put it on a dyno, run it for about 5 hours at a light load and as you get closer to 5 hours, you need to change the oil, and you can work the engine a little harder. Keep a sharp eye on the plug colors and engine temp. White plugs mean lean, black means rich. It just takes time,,,, be patient, try to keep the hot rodding to a minimum till it gets about 10 hours on it. Chad
