They claim they are like the old double hump heads.
They are definately priced right.
What do you think about them?

The numerical specs match the double humps. That's where the similarities end. These are modern heads with vortec-style combustion chambers. The smallish intake runners mean good midrange performance (where most of us drive). They would be a good match for your cam.

Good Post...I'm planning on rebuilding my stock L-82 real soon and I was looking at these heads also. I'm NOT going to pay big $$$ for the other brands. I just want a nice weekend cruzer...

Most of the old DH heads have been previously abused and a quality re-build would either not be worth it or cost prohibative.
For a little more than $600 these seem to fit my goal.

summit heads
Me too. I'm not a racer or anything...A buddy of mine has a set of 041 heads on his vette and it really seemed to wake up the L48 over the stock heads.
Most of the old DH heads have been previously abused and a quality re-build would either not be worth it or cost prohibative.
For a little more than $600 these seem to fit my goal.
