I was wondering if anybody has ordered the L98 aluminuim cylinder heads from this company?

I want to keep my car emissions legal (89 Iroc w/350) most of the other company have cylinder heads with large combustion chambers (68cc/72cc) which would lower compression?? Also most of the companies don't have the emission provisions?? The car is going to be strictly street and I don't want to loose the low end power and torque.

I was also wondering about the zz9 cam from the same company? Any comments?

I am aiming for 300 hp, stock hp is 230 so hopefully it will not take to much to hit the 300 mark??

 

Other companies offer the same products at way lower prices.
TPIS has a reputation for selling other mfgs poducts at hgher prices.
