El torro + which heads??? ok guys since im set on the El Torro cam for a cam swap down the road i was wondering If PRC stg 1.0 LS6's or PRC stg 2.5 5.3 heads would be better for the streets? is there anything that has/needs to be done to the heads to make them work with El Torro? does anyone even have heads with the El Torro cam? sorry for the long post but search is NOT working for me 
thanx guys

I would recomend Livernois stage III, LS6 heads. The have 220cc intake runners for good velocity and the LS6 castings speak for themselves.
5.3L castings will work but you have to be careful about intake valve choice (2.02 max on unmilled heads) for plenty clearance.
Some valves have thick base (like Ferrea) and reduce PTV by as much as .020
Another good one would be TEA stage 1.5, 5.3L

Another vote for TEA 1.5's.
My girlfriends car has trapped 120mph many times with these heads and a 224/228 cam in her A4 Z/28.
My C5 with our stage 1 CNC heads, 224/228 114 cam, Longtube Headers & X-Pipe, and CAI went 120 mph in the 1/4 mile.
Thank you for your interest, please let us know if you have any other questions.

its all good meng 
I believe from what ive read when i had the eltorro cam its is more specd for stock heads. I believe predator has a 230 232 he called el torros big brother that he specd for heads that was suppose to make some nasty power

14* overlap (nasty lope), abit less trq below 3500 than El Toro, but more in upper rpms. Trq curve is just as flat as its little brother. Good week end strip cam and it likes 100>150 shots of gogo juice
