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!!

They do look gorgeous! Any problems installing on the smaller bore LS6 motors?

What is the out of the box CFM? What is the valve size?

0Bob@PrecisionPorting

2.20" valves, and they flow very well... But We're anxiously awaiting the LS7's from World Products. They will be a better price and better performing head (with C5R exhaust ports too!). They are due in about a month. That's the ticket. We will be working on them for a retrofit to LS1's because of the smaller bore and valve shrouding problem, using the more normal LS1 size valves.
