LS7 Heads hit the door - Pics inside!

We are happy to be among the first in the country to have access to the new GM LS7 cylinder heads. These heads are really nice... We have taken photos with them next to LS1 heads to show the differences. While these LS7 heads from GM are a big improvement, we will be providing an even better set of heads for our customers soon. The highly anticipated World Products LS7 Cylinder heads will be available from us, as well as their new LS blocks! These heads employ the C5R style exhaust ports, huge valves, incredible airflow and port design. The World LS7 heads will be priced below the GM LS7 heads, and provide even more power.

Until then, enjoy the GM LS7 pics!!

PICS at:

Thanks!
Bob

I haven't really paid much attention to the new LS series. Will these bolt to an LS1 block as long as you use the LS7 intake?

If you use the stock LS7 intake valve (2.20"!!!), I've read you need a minimum of a 4.060" bore. I actually just emailed Precision Porting a second ago asking if the heads would work on a 4.000" bore LS2, with a smaller valve. Largest valve that usually comes in a ported LS1 head is 2.08". I dunno if that would work in an LS7 head, or if the valve seats would be way too big for it.

Bob,
Very interested in the World Products LS7 Cylinder heads since these should work fine with my LG longtubes, right? I assume the WP heads will accept an LS7 intake?
Thanks!
Vaughn
