Not for your stated 450hp goal.
this particular cylinder head is good quality but the out of the box air flow is modest-lame at just 209 cfm. (flow bench verified) Its needs a lot of porting work to correct to get even near a 450hp capable cylinder head. This is not a Platinum series head.

Pick a true Platinum series head if you want a 450hp capable Dart head.
200cc 215cc etc. The 180cc Iron Eagle head is lame. Bad choice for out of the box high power.

it's not what you want.

Does it have to be a certain cc or have certain size valves or what??????

you need to define what you are trying to build.
How many different threads are you going to start on this same engine.?

It might be on the same engine but its different topics man. Im not gonna talk about heads in a crank message board. Someone might know things about heads but not about a crank. Stop whining or dont comment

I guarantee that attitude won't get you far here.

i love DART and it pains me to say that the older style iron eagle DART heads are just that, old and out dated. the new platinum heads are a great head, had a pair of worked over 200cc. made great hp and tq on a 385.

now what cam are using, as this in my opinion is what you should build the rest of the motor around (besides it's intended us, that should be first).

Sort of obsolete, at the price their asking I guess this is cleaning out the warehouse.

These would be OK for a mild street build or as stock replacement. The 64 cc chambers will push you into a dished piston. If you're building a hotter street build or headed for a race class that allows porting, these puppies port up real nice, lots of meat in the walls, it's almost a requirement to get them to work well.

The combustion chamber is a little behind the times, some nice features but the spark plug location is slightly off ideal, aimed at the exhaust valve and a little deeper toward the center between the valves would be better. But all- in-all not a bad head for the price especially if you're build isn't intended to be setting in the winners circle every Saturday night as more modern designs have just enough power edge that if it comes to gun down, these are the number two finisher.
