newmans with soild lifters, i'm using 1 in an cvh xr2 (phase2 cam) with 40s, head work ect and goes really well cam only really kicks in at about 3.5k but revs to just over 7k.
also using one in the turbo again with soild lifters and from a near standard engine (air filter, exhaust, front mount) after fitting made 13 bhp more and rev that bit harder.

the only thing is that the lifters are a pig to do so if your not doing it your self could cost quite abit just to set the lifters up.
