Does anyone have a part number for some replacement stainless valves? Either that or specs on the stock stuff so I can search?

I think the head gasket on my stroker has a small leak and the machine shop did a crappy job on this cylinder head any ways. I am going to have another one rebuilt and might as well add some performance where I can. Thanks!

SI Valves SEV-3954 for SS intake valves. Don't know about the exhaust.

those are 1.625. thought it was bad for our motors to increase exhaust valve size?

Its not good to increase the valve size due to valve shrouding by the combustion chamber and cylinder. I have also never seen any proof that larger valves help in any way.

Not looking to increase size, just go with a good valve that is a little better flow. My barracuda picked up .3 in the 1/4 just changing from stock valves, figured it couldn't hurt the ole jeep much.

Hesco has some valves too, but they aren't cheap.
