The TMH headers ..... also fit aftermarket aluminum heads.
They may fit some aluminum heads without modification but not all. Both of my aluminum AFR heads needed a little mill time to provide clearance for the collector on the PS and for the flanged joint in the #5 primary on the DS.
The sides of the original iron head castings have recesses between the external head bolt holes and these accommodate the tightly tucked TMH's. The AFR's have a thicker, flat casting in the same area and that's what causes the interference.
Not a big deal, just something to check for. If your Al heads have a clearance issue like the AFR's, it should be easier to deal with before the heads are assembled to the block.
