I own katech cnc ported C5R heads with pro series jesel rocker set!
this is CRAZY! "Very very nice set of c5r race heads from katech . these were development heads for the compuserve corvettes . these were developed for there 427 inch motors to make alot of tork to come off the corners for a killer road race head . these take a 2.150 intake and 1.62 ext both 11/32 stems . heads have berillium copper seats and bronze guides . the intake ports have epoxy in them to mold the port the way they wanted its a very trick intake port . these will work on any ls1 ls7 ls3 block . castings cost 2600 from gm and these are alot beefier than a stock ls1 ls7 or l92 head there made to take the abuse of racing ." |

Good find! Came with valves, or no? And do not, under any circumstances, run alcohol through them. Also, bolt a head to an empty block, put some layout fluid on the deck of the cylinder heads, and scribe around the bore so we (I) can see how close the chamber is to the cylinder wall.

That's not the school's dyno, and if it is that was YEARS ago... I think it's someone else's dyno, possibly Stacy's, used to be an instructor there.
That was before the belt drive, front drive for the crank trigger, and crazy ass twin throttle body sheet metal manifold. The school's dyno is much MUCH nicer than the one in the video. And in the vid they turned it around 8500. They twist it a thousand higher now. |

Duration at .050 specs out past 300* on the exhaust but with the big induction on it now they might not need such a big cam anymore. |

got some c5r valve covers now too, but the bad news is my hospital visit is forcing me to sell.
If anyone knows someone who might want these help me sell them please. http://cgi.ebay.com/ebaymotors/ws/eBayISAP...em=290299208795 and if anyone is building an ls3 motor: http://cgi.ebay.com/ebaymotors/ws/eBayISAP...em=290299214621 |
