Absolute Speed 5.3 Stage 2.5 Heads (pics) Absolute Speed stage 2.5, 5.3 heads with rev 2.055 - 1.60 valves titanium retainers Comp 977 springs good for .630 lift. These heads were CNC then hand finished. Have maybe 7,000 miles or less on them and flow sheet will be included. I payed $2495.00 shipped for these things when they were the newest thing put out by Jay@Absolute Speed. The car dynoed 436 rwhp and 404 rwtq. With these heads and an FMS F-11 cam the car has gone 7.26 @ 98 mph in the 1/8 (on motor). Car was @ 3500 lbs with me in it. On a 150 shot the car has gone 10.49 @ 133 mph with a 6 speed. It has gone 10.38 @ 130mph with the TH400 and 150 shot. The heads were pulled off and sent to LME to be checked out. They are fresh out of the machine shop, with new seals, valve job, surfaced, and hot tanked. I pulled the motor out, to put an LME 408 with ET 255 heads in.I am asking $1400.00
