Absolute Speed 241 heads
Absolute Speed 241 heads Picking up a set of Absolute Speed ported 241 heads off a friend of mine who is goin with L92/LS3 style heads for his build. I don't know much about these heads...anyone got any info on them?
They are a pretty good head for the money. I have a buddy with an 02 WS6 with Absolute Speed heads, TR230 cam, 90/90mm FAST intake & TB, LTs, Lid, U/D pulley, 12 bolt w/4.10s and runs
11.3 at 123 Full weight other than the skinnies up front. That was in really good weather and driving like a madman. He dyno’d 425rwhp I think. Thru a 10 bolt it would be close to 440 rwhp.
I had a set Absolute Speed stage 2, 5.3 heads + Comp 230/230 XER cam, stock LS6 intake, stock ported TB, Lid, LTs, U/D pulley and made 430/400 with the stock 10 bolt in place.
I ran 11.9 at 120 leaving the line like gramma since I was still on the stock 10 bolt and 4 hours from home. Driven to and fro.

I have heard great results from these heads...I have a couple friends that have had them and love them. Just wondering if anyone had any technical data for them. They seem to be great heads!
Friend picked up 36 whp (430whp 395wtq) from the added compression and port work (62cc from ~66 stock 853's). This was in a vette with a 228 232 xer cam and ls6 intake stuff. Solid gains.
Anybody else with good info? I did a search and found some threads, but not much tech on these heads...chamber size, intake and exhaust runner CC's, flow numbers...?

If they are $600 there is no question get them. On a side note years ago when first came on here they were selling these heads like hotcakes advertising 300+ cfm numbers. One day I caught a picture they posted that showed a head being flow tested, I call them out about the flowbench. It was a home made job painted like a superflow. Since I own a superflow I knew better. They admitted to it and a few months later posted where they bought a superflow finally and their heads didn't flow what they thought. Not that they didn't perform okay but not what was advertised.

Yeah, i know...thats why I was looking for some good info on them. I know they made some nice power back in the day. Like I said, I have had two friends use their heads, lately, and did really well. both sets were 853 cast heads...so I wanted to see how the 241's compared.
