noisy slant 6

i have a 225 slant6 and it makes a little noise. i read the thread on 225 vlave adjustment. i need to do that, among some other things; change oil pan gasket, replace the engine mounts, replace fuel pump gasket, intake gasket, exhaust gasket, the carb gasket, gasket in between the exhaust and intake. i already replaced the valve gasket. there are a couple little oil leaks very minor, maybe have to put a quart in once every 2 months or so. i thought it was an exhaust leak at first, so put some exhaust weld on the flange between the exhaust manifold and the tailpipe. still makes some noise. everyone told me that it was kinda noisy due to the valve train rod. the noise it makes is a little deeper then a valve ticking would be, but not as deep as a rod. is it something that i just need to get used to, or is something up. :help:
