I'm considering replacing the top end on my stock 1996 MAG 502MPI, (Black motor). I'm Looking at cost and performance so I think it may be a better choice to go with a new set of alum heads rather them gone through the originals. I's to keep it close to the original 8.75:1 compression. with so many choices out there these days, I'm looking for a recommendation on brand part number. So far it looks like Brodix makes a decent product. Not seeing the same reviews for Eddleborck.
Thanks

Call Teague. They'll get you set up. I believe they have AFR and Edelbrock options. Both with hard anodized jackets. Even the Colorado river will cause aluminum heads to corrode a little and I have seen the most corrosion on the Brodix heads. They will have a cam selection to go with your set up too.

Call GT Performance. Gary has plenty of great combos depending on budget/needs.

I'm curious why you want to stick with the low compression? You can easily get away with more with aluminum heads in a marine application.

Thank you folks. I’ll give both Teague and GT performance a call.

Thoughts behind sticking with lower original compression: ability to run on pump gasoline offered in California. I don’t mind running the 91 octane, it’s just the crappy gas that’s available here . Do you feel I could get away with 9.5 to 10:1

We're running 10.4:1 on crappy CA gas. Aluminum heads and endless amounts of cold water to cool the motor really helps.

Ok I’ll definitely consider it; next to using the right cam, that Is probably the most efficient way to gain HP.

The edelbrock head are a good piece. Edelbrock makes the heads for GM that are on the 525 efi motor.

If you match a cam and tune we prefer a Brodix bb3cnc snd our calibration. Edelbrock is good if you not changing much
