Thats nice. $:-\$

edit; mis-read sorry...

Any rectangle port heads will work on a mild build, but.....combustion chamber shape and size by itself don't mean anything without the proper piston dome shape. Right heads wrong piston can spell disaster for any build. I always recommend buying pistons to match the head, not the other way around.

The only thing I don't like about rec. ports is the RPM range they like to see (IMHO not worth a damn under 4000 RPM)....

Same as 990's and also should have a better seat design (later head). But I think 118 cc chambers on the 990's?

These are "service replacement" heads and make good heads for high RPM HP....

If memory serves, they have additional accessory bolt holes in the ends. According to the GM bible.
