topend upgrade

i know the zz4 is the recomended cam but is the zz9 cam worth the money?
and if i go with the zz4 cam and beehive springs what should i do as far as heads and intake? should i stay stock and have my mechine shop modify my heads, or is it better to just buy a trickflow set?

Actually, if you get the specs off of TPiS' website, then you can give them to Comp Cams and have them grind the cam and get it a lot cheaper..

Re: topend upgrade

imho, I would upgrade the heads *if* your mileage isnt real high. You can get the Vortec heads, but then you have to get the Vortec base, which is a good thing. hth
