#4448308 heads have any potential?

You need to have the heads looked at.

If the guilds are in fact bad replace them. Its needed for a tight valve seal that last.

5 angle valve jobs are not needed. Sure the heads might flow a bit more but guilds and a normal 3 angle valve job will last a long time and still flow ok.

I would skip the 2.02 intakes unless the intake valve need to be replace-unlikely.

Same with harden seats. Even heads without any type of hard exhaust seats will last a couple of years before the valves sink.

So I would have the heads disassemble and new guilds and a performance valve job and new springs and retainers-locks too.

I agree in ways, it's a tough decission to make between a 5 angle and ...I mean, in most shops out here they pretty much do the 5 angle on anything performance based..it costs around $175-$225, yes guides are a must, for they won't do the VJ if the guides are trashed..= centers the chuck.

as for power/flow...well we do know that just cause the heads flow 240 doesn't mean they do after the inake and cab go's on, so....this is where exaggerating the flow beyond 240 to like 250-260 in order to get an actually 240'ish port flow with everything bolted up.

every 5 cfm is worth 10hp, so add up what you need for your goal and keep the rest in mind for how much extra you'll need.
oh and.definitely do the hard seats, they'll sink in 10k'ish of hard [wot] driving.
