Comp Cams 08-412-8 + S/R Torquer Heads?
I am currently rebuilding a '87 305 and planning (hoping) to run a Comp Cams Extreme Energy Hydraulic Roller Cam 08-412-8, it has .495 intake lift and .502 exhaust lift. Using a 1.5 rocker arm ratio its valve lift would be .742 intake and .753 exhaust. World Castings S/R Torquer heads are listed at max lift of .56. Is it possible to get the two to work together? If not can anyone recommend an alternative head?

You got it confused. The lift spec listed is the lift at the valve
with a 1.5 rr. .495/.502" is the valve lift. Th cam lobe lift is.330"/.3346"
