Budget cylinder heads for a 318

Hello everybody. I've been out of the car scene for awhile and I'd like to put together a 318 for fun. Not looking for a lot of power, something like 300-325 at the flywheel. Thanks
I'm mainly looking for a fun car to drive and thought that a 318 could make decent power.
It doesn't have to make 300 at the flywheel, I thought that would be a easy goal. If the car I find has a 318 already in it then that's good enough for me
I do have a budget that I would like to stay at, but I don't want to have to re buy parts either

I don't know about "325hp out of a 318 ain't no small thing" guess depends what you mean

"325hp out of a 318 ain't no small thing", means; principally, that it costs money. and with bolt-ons, as you know, the fun-factor is delayed..... unless you spend even more money now on the chassis.
