Blown 509 head recommendations
 

I want to upgrade the heads on my engine.
Currently running stock rec ports with inconel exh valves.
Setup now is 509ci,8.75 compression,hyd. flat tappet cam, B&M 250 blower(6lbs boost),Nickerson preped dominator,gil exhaust.
Considering:Dart iron eagle,Merlin(iron) and Edelbrock aluminum.
What do you guys think?
Of course I'm looking for the most bang for the buck.The eldebrocks seem like a good deal,anyone have any experience running them with a little blower?
Any one have flow spec for the iron eagles or merlins?(310-320 runners)
Thanks,Jeff

:D :rolleyes: if your using a 502 block with angler shape water pasages at the head and , youal probabuly keep blowing gaskets.. if you have round water passages,,i think your ok.... blocks with anguler passages dont like blowers. :bunny: :bunny: :bunny:

Go with the Canfields.Nice head and inexpensive.

I used Brodix BB2 Plus in a similiar setup dynoed 805hp and ran great.

Thanks for the replys.
50boat, I'm using cometic gaskets and am not having sealing issues.I'm looking for new head recommendations.
I boat in salt water so if I go aluminum they will need to be hard anodized.
Who sells canfields or brodix hard anodized with inconel valves in them already and what do they cost?
I dont want to spend $2500 on a set of heads.
I was looking at the Edelbrocks because for about $1400 you get the inconel valves and anodizing,I know I'm gonna have to add springs,retainers, etc. to them.
I'm still looking for flow #'s to plug into desktop dyno.
My goal here is somewhere in the 600-650 hp range,gotta keep it somewhat tame for the family
Thanks

Brodix will upgrade you to Manley Inconel and they should run about $2200 fully assembled ready to bolt on. The website has all the flow numbers listed at Brodix.com

Good Luck!

The Iron Eagles are a great deal and flow very well. I would pick them for salt water. Jim V can make them flow 400/300 at .6 lift.

Re: Blown 509 head recommendations
 

Jim V would be a great guy to talk to, he has heads and can improve most others.

profile you should be close to your goal with what you have.
