My Conversion Project, Question on Engine Break-In Options

[Ericv1]

To try to make a long story short, I acquired a 70T with this engine 2 years ago. I cleaned the engine up, got it running to find I had low compression in cylinder #1. When I pulled it a part, I found that #1 had a blown head gasket. I pulled the three pistons and cylinders on the 1,2,3 side to clean off the carbon. I had the heads checked out and the heads and valves, guides etc were in spec. I accidentley broke an oil ring attempting to take it off and clean the piston. So, I ordered a new set of rings and have successfully put them on cylinders 1,2,and 3 as well as alot of "while your in there" gaskets to reseal the engine. So here's my question. Is it necessary to rering cylinders 4,5,and 6 with the new rings as well? Those cylinders had good compression before I tore down the engine. They were all in the 150-155psi range. I've rebuilt a type IV engine before but never a six. But I have Wyanes book from the bird board and have read it several times. Thanks in advance for your assistance. By the way, this engines going in my 74 teener and will be a nice summer/spring project. java script:emoticon':wavebye:', 'smid_58')
