i have the indy maxx aluminum block with Stage V heads, problems with the TTi headers and alterktion front rack & pinion motor mounts
the main bearing cross bolts hit the headers (2 1/4 primaries), the motor mounts hit the cross bolts, the headers hit the power steering box, the headers hit the flaming river steering shaft universal joint
a good hammer fixed everything, now the starter has to go on, oops take the header off the driver side first & then install the starter - duh
