Well i just bought these heads a few weeks ago and had them looked at by a few guys who have porting experience and the said they looked damn good. they do look great. all porting work was done by absolute speed. with a 224 cam and these heads and ls6 intake. the previous owner laid down 415rwhp to the wheels. its got comp 918 springs with titanium retainers which have low miles on them. these springs wont hold my cam so i'm going to just get a set of of 5.3 heads for the higher compression with .650 lift springs. flow numbers on these heads are as followed...

lift - int - exh
200-151-115
300-207-163
400-259-206
450-276-212
500-288-221
550-298-225
600-307-228

if they dont sell then i'll just buy new springs so they wont be for sale forever

$750 shipped to you

 

pics coming tomorow.

 

what are the casting #'s on the heads? how many miles on the heads

 

they are 241 casting number heads. and they only have seven thousand miles on them.

 

pics added.

 

bump for today

 

bumppp. shoot me an offer if interested

 

found a set of 5.3's that i'm ready to get. i'll take $700 shipped. these are a great set of heads. i just figured instead of me changin the springs that are perfectly fine and milling them it would be better to sell them to someone who needs them as they are. that way you don't have to take to machine shop...etc..

 

Jay did some good work back in the day. Chances are I did the sandroll finishing work on those heads. My AS 5.3's are 8 years old and I transferred them onto my LS2. I made 455RWHP on a stingy Mustang dyno thru a Moser 12 bolt and a Circle D 5K stall non locked converter. This combo (listed below) thru a 6 speed on a dynojet would lay down 500 to the tire.

 

thanks for the backup man. yea i read for a while to make sure i was gettin good heads and everyone seemed to talk pretty highly of jay. that's who i figured out did the porting. but like i said i had a few guys look at them and they said it looked pretty damn good. i just got some more unexpected money so i'm gettin a cnc'd 5.3 head for a little more compression. otherwise i would run them. if anyone is interested make an offer i cant refuse.

 

What part of SC are you? I am interested in these and pick-up may be a posibility shoot me a pm or an email(easier since I am on my phone) and we can talk about it
