isn't the stock gasket something like 1.1mm? i highly doubt it would make any difference to the chain at all, the tensioner will take that up. tomei 256 cams drop straight in.
the cams are in... well that's about the only mod stuff you can grap from tomei.. 0.7mm gasket and 256 pon cams.. i am planning a polish head with a new tomei gasket .. was just thinkin if any valve adjystment is required... would like to ask for opinions from you hardcore guys out there?
