If the cam and crank are not timed properly it would probably affect all cylinders the same not two cylinders but anything is possible. I'm wondering about the remote chance the cam was ground to an incorrect valve opening sequence that does not match the firing order. Also wondering if the valve springs might be weak on those cylinders, if original they are approaching sixty years old and may have been the ones fully compressed for over 4 1/2 years.

Good luck...this one is interesting!!!

hi, wondered that myself,thinking i may have got timingchain out 1 tooth, but as suger bear said in his post would probably effect all cylinders not just #5 & #8,but don"t mind being corrected if anyones had a similar problem thanks brad
