motor is 454cubes and 10.5 to 1 besides AFR and looking for something with stock location exhaust ports what whould be ur pick

 

For what rpm range? Iron or aluminum? Budget?

There are plenty of good BBC heads out there, but you need to be more specific about what you have in mind.

7k rpms give or take 500 havent descided fully on what cam im gona go with yet. iron or alum dosent matter budget is 2000$ on heads

 

What size engine are you running? If its not a huge monster, 540+, you can still make huge power with a set of worked iron stockers.

 

i got ls7 heads on it now ....looking to upgrade....i found a local macine shop thats currently porting(not full out race just cleaning up the bowls and exhaust) a set for another guy and i will have some flow #s from him late this week early next week

 

$2K heads on a 6500-7500 rpm 454 probably won't get you much. If you have $ for the bottom end which will take 7500, you might consider a 6500 max engine and spend some of the bottom end money you'll save on airflow. That's where the power is.

Cam is the last thing to specify.

Have you lifted an iron BBC head lately? They make good wheel chocks for large airplanes.

 

Some 049 or 781 oval port iron heads work very well with some 2.19/1.88 valves installed in them. I ran some 781 heads for a couple of years until I dropped a valve. I went with some Merlin oval port iron heads for a few years after that.

For the majority of all racers out there who have an engine that stays well below 7000 rpm, they don't need large retangular port heads. Oval ports will work much better for most applications.

The best bang for the buck for aluminum heads is Canfield however the castings leave nothing for improvement. If you want some aluminum heads to hog out to ProStock sizes, pick up a set of Brodix. My current engine just got a set of Canfields however I don't get a chance to test them until May!

As mentioned above $2k doesn't get you very much for BBC heads. I don't even want to price out how much is invested in my aluminum heads

Canfield 310 heads
2.25/1.88 stainless valves
Titanium retainers with 10* locks
Triple springs (set for .800 lift) Cam only lifts to .722
Comp ProMagnum rockers
Reher Morrison stud girdle

 

I'd get the LS7 heads worked over if my budget were $2K.

Off topic but....I looked at a set of Dart Big Cheif BBC heads on the net the other day and all i can say is.... DAMN. If $$$ were no problem, i'd pick those up. lol
