I am building an 89 302/5.0 block using forged pistons and rods and the Ford cam E303. I was wondering which roller rockers I should run with this set up?? Aluminum or Steel, 1.6 or 1.7?? Any thoughts/experiences would be appreciated. I am also wondering if I should use the stock heads with better springs and rockers, spend about $600.00 to have my heads worked on, or get a set of the GT40 heads?? I will be running a Garrett T4 turbo also.

Thanks, Earl
