I bought a set of used SHM heads and cams and I'm in the process of installing them.....now, the heads are aluminum....and the stock GT block is cast-iron (right?) since cast-iron doesn't expand as much as aluminum when heated, is this going to cause any major problems? I don't think it would because aluminum heads on a cast-iron block is old-school hot rodding but I just wanted your opinions...thanks in advance!
