-Finally the cams. Earlier Alekshop got like 24whp just from changing cams to 284s, but their graph still doesn't look good and drops off a lot at high rpms. The 292s avoid that. If they made 304s that accept Vanos I'd consider them as I think there is more to be had, but I'm not willing to lose Vanos to gain hp.

I'm sure Karbonius and Headers really shine on this build. I've always wondered my nobody does head work on these cars especially NA, at least I haven't read about it.
