Hot Rods Hemi exhaust

Question for 354 Hemi people. Has anyone tried using 5.7 Hemi exhaust manifolds on a 354 Hemi ?
they look close but don't know if ports and studs would line up.

 

I never tried to modify, but they dont look the same. Maybe buy a set of gaskets and compare for sure?

 

the factory stuff were the first block huggers,,,,,,

 

This is off an old HAMB forum. Above is from Hot Hemi Heads

 

Nope.

There's SEVEN bolts (three bolt holes on the bottom and four on the top) on an early head and eight on the late heads (four on top and four on the bottom).

Totally different

 

Thanks found out. Sold the Hemi
