Sorry guys didnt realize the "follow the link" thing would be a problem. I do a lot of posting from a pda phone so just trying to save a little time.
The combustion chamber size is the stock 54cc or whatever it is minus whatever for being milled. valves are probably pbm whatever the shop used but I can tell you that my motor before self destructed and bent 11 of them when my cam broke and none of them broke. my new trick flow heads have the same valves and I am running .709 lift with 270 duration @.050 running 11.20 @125 so I am very satisfied with them. springs again probably pbm (which are probably comp or crane marked generic) again those are what I have on my new setup. No flow numbers and they are not polished on the exhaust side anymore due to being bead blasted at machine shop to clean. They were ported by the machine shop NOT all out ported. All I can tell you is the numbers I made with them on my old setup and that they are solid and new. larger exhaust valves ready for someones cam swap. casting numbers are.. 10207643 from what I can tell.


Here is the post....


I have a set of LT1 heads that are fresh from the machine shop. They have 1.94 intake valves and larger 1.60 ex. valves. Stainless steel swirl cut valves. Springs are good to .650 lift comes with 7/16 screw in studs and isky adjustable guideplates. I still have 15 of the 16 hardened pushrods too if interested.
Heads are cleaned up as far as port and polish no extensive work but are mildly ported. I ran a 12.03 @114 on stock shortblock, full weight car with edelbrock shorties, ignition box, cc306 cam, and 1.65 roller rockers. made 369 rwhp and 368 rwtq on the dyno.
These are the heads I used before I built my 408. I had them rebuilt for my 3rd gen LT1 swap and then sold the 3rd gen so looking to get rid of them. I would like to get $800 o.b.o. for them I just spent $400 at the machine shop on them. pm me or email me at areelice@gmail.com if interested.
Thanks for looking...

 

Combustion chambers are 52.5-53cc's. these are perfect for someone swapping cams. no need to change your springs. have them ready to install do it all in a weekend.
