stick with standard cams and standard compression, but valve cut outs are always a good idea even on standard cams & compresions.
most standard cossies have had piston to valve contact, so valve cuts out are a good idea
t34.63 with blacks and other supporting mods should see a very strong 380hp.
just make sure all the basic things are done right, eg. rewired fuel pump for a direct feed from battery, 30 min job, cheap and essential!
