im sure this has been dicussed, but since we're on the topic, whats a tried and true aftermarket head for the magnum 5.9? has anyone had problems using aluminum on a DD?

 

There's RT heads, EQ heads, Edelbrock aluminum heads, and hughesengines.com makes a stock replacement HD head that flows better than stock. You can get a set of the hughes heads for under $400 and build them up if you know how.

 

well the hughes heads are under $400... each, but their bare, you still need valves (lapped), springs, retainers and keepers, but its still not a bad deal. The 2.02 with swirl polish are just over $1000 w/o springs keepers and retainers and they flow better than the Edelbrocks.

 

which ones are you talking about? i know nothing about heads. what kind of gains can you expect from the heads you are talking about? can you get some that are just bolt and go? already loaded with everything?

link me to those 1000$ heads. maybe something i might be interested in. thanks.

 

DH, your years are slightly off....92+ 318's are magnum, 93+ 360's are magnum. (possibly not in all applications, eg. van's and heavy duty's, but for regular pickups).

 

oops.

 

is this the heads you are talking about?

Those dont look like the Hughes heads do they? the CC has a different shape than the standard mag heads IIRC.

 

those are the same heads ive purchased..alot of meat to them..more so than r/t,s and allow for a good,,good bit of p.ping...

 

whats p.ping? port and polishing?....... do you have them installed? if so,how are they? would i gain much without changing the cam? gonna be supercharging at tax time if that makes any difference.
