doing a compressin ckeck will help aid in finding a valvetrain problem. is it a mechanical or hydraulic cam? what are the cam specs? what kind of plugs? i run motorcraft af42c in my clevland. dont use bosch(=junk) if there campions and they have been fouled once replace them. there should be idealy no more than 10 percent difference between the highest and lowest cylinder. check all 8 cylinders.

let us know
