Bore
Damn! It is the bore that's the difference! The 3100 has an 89 mm bore and the 3400 has a 92 mm bore. Guess that means I can't use the heads from my 3.1 on my 3.4. Does anyone think they could be dished out? I couldn't find specs on the stock heads anywhere. I'd have to see the difference in cc's. I know the intake valves are the same, I'm not sure about the exhaust.
