will my Hooker Comp SB headers for Chevelle fit my brother's (future)SB powered 69 Nova? Summit/Hooker shows the same PN but anyone know if they'll have to be "massaged" to fit the nova? (we'd rather ding my old ones than a new set if we have to ding them)

With an 1 5/8" header it may just work. With a larger 1 3/4" tube, I seriously doubt it without mega bashing the tubes. Them nova engine bays are pretty tight.

my nova headers fit my 66 chevelle so there is a good chance they will

hooker competition headers 1 5/8"
part# 2451 will fit:
67-81 camaro
64-87 chevelle/el camino
70-81 monte carlo
68-79 chevy nova
65-89 fullsize sbc

thanks a lot guys.
