absolute speed st2 5.3 heads
I am selling my absolute speed heads and comp chromemoly pushrods (7.35 length). The heads are milled 5 thousands and have comp 987 dual valvesprings. They probably have about 2-3 thousand miles on the heads. They are supposed to flow 310 at 600 lift that is what i was told when purchased.I did not get a flow sheet. I made 445hp and 389tq through a 9 inch with these heads.1100.00 shipped. PM me with any questions. Thanks.

I just may be intrested in these heads. I am just starting to read on what heads will be best for my set-up.
I have a 02 Z-28 A4
I have all the bolt ons with LT headers, y-pipe with hi-flo cats, 224/224 with 570 lift at 114 lsa, 3,200 stall with 342 gears and tuned by Jeff Creech.
I am in California so I need to stay clean enough to pass the sniffer. It passed with no problems with my mods so far.
Any input of these heads for what I have would be much apperciated.
Thanks

Fire chicken-Before the heads i made 408hp and 366tq through the stock rear. Then i added the heads and 9"rear at the same time and made 445hp and 389tq. Not sure how much more the 9" takes away. I would say at least 10hp.
Blown v8-I dont know about the emissions. We do not have emissions testing here... But i do know these heads would definetly help your combination out. There supposed to give 11.1 compression.
