Ok, my poor Z28 either blew a head gasket or cracked a head the other day. So I am going to take this opportunity to improve the performance. I am aiming for low 13's to high 12's if possible. I am on a sort of tight budget too. First off what heads and head work should I go with? I am taking all the emissions crap off and I am getting headers and roller rockers. Other than those mods what are some suggested "cost friendly" mods I can do to help me toward my goal? The engine is '91 L98 350TPI. Any help would be much appreciated.

 

Anybody have ideas, it would be much appreciated, thanks.

 

vortec heads, sdpc base, 1.6 rockers= a very solid package\
