ttt.........

 

chamber volume? how much, if any, have they been milled?

 

They are unmilled. The chamber volume is 64cc according to TEA....

 

ttt...........

 

what size are the exhaust valves?

 

Stock LS1 1.550 Exhaust Valve (REV 1.57” Exhaust Valves are also available)

Same as the LS1 heads......these will yield higher compression without milling, and have great port velocity making them a great street head.

 

top for tonight........

 

ttt.............

 

still available....

 

What did you request the chamber size to be when you ordered them?

Do they come with the head gaskets? If so, which ones? MLS, Graphite, thickness?

 

They definitely look nice. Bump.

 

They are unmilled, and although I didn't measure the chambers myself, TEA said they are 64cc. Stock 5.3 heads are 59cc (I think) but they are opened up for the larger valves.


If I get my asking price I'll throw in some stock MLS gaskets.....

 

top for today...........

 

I'm going to recommend these to my buddy. I have the same setup and am very happy with them. I made 422 RWHP through an LS6 intake and smaller cam with these heads.

Great heads, I have a set of TEA Stage 2.5 and just pulled a DYNO 444 RWHP with 423 RWTQ out of a 111k mile bottom end.

Great deal on these Heads.
