aluminium head questions

Cost to go to a roller cam on my race car.
Cam $350,over .700 lift
Lifters $500
Push rods $160
Springs Retainers locks lash caps $500
More head work,$500
T&D rockers $1269,needed for cam,spring and head combo.
All this to get 1/2 second.

T&D rockers ie race car ****




Took off Crane rockers because they won't work on the Indy heads I have,the geometry was off.
These are the rockers that came from Muscle Motors and they were not right from them.
So remember check everything twice,I ran this engine 200 pass's and bent 6 push rods.
The sweep over the valve tip was off.

These are the diff rockers we tried.


Wrong rockers,retainers,locks and rockers.Mass $$$$ mistake.
