Hey guys I have a question yall may be able to help me with. I had my heads ported, polished, and decked and they did a valve job as well, but kept stock size valves. Can i put 1.90 intake and 1.585 exhaust valves in without having the valve seats recut, and can i replace valve guides without having valve seats recut? Thanks

No to that, also.

So what do I have to do to install those valves? I thought i could fit 1.90 valves on stock seats?

You can but you have to get the seats cut for the OS valve. The heads should be ported to take advantage of the OS valve.
If you replace guides you have to get the seats cut.
Do it all at once.
