the best is to support the moter up with a floorjack

mount the headers and if you cant use the mounts use a moter plate and take it from there


my 440 with 906 ,stage 3 max wegde heads and stage 6 heads where no problem


when I went to indy sr,s all I did was lowwer the moter down 3/8 and they fit great
