Tim:
Exhaust manifolds on this one. I do have a really nice set of headers from a small company that went out of business in 2009 on the car right now running an L46 (HW code) converted to LT-1 specs. Magnaflow system from the headers back.

I suppose it is POSSIBLE that I change my mind again after putting the 302 in and running stock manifolds and stock exhaust. I doubt it.

At least for NOW, planning original manifolds, gutted smog pump, with all the smog pieces in place and stock exhaust, meaning two resonators and the transverse muffler. I have all the original hangers for my car and all NOS exhaust from the mid 70s.

"...make sure whoever does it does the unshroud cuts on the intake valve area in the combustion chamber."
Dave; that is part of what I meant by doing it correctly. They need to LOOK exactly like factory 2.02 heads when done.

Not concerned with converting to screw in studs. Z/28 did not have screw in studs in 1969. While I might drive it a little hard occasionally (I do now) I don't see living at 7,000 rpm. Doubt I will ever pull a stud. Could always pin them. Did a bunch that way back in the day.

I already have a pair of 186 heads fully ported, screw in studs, true 2.02 heads ready to bolt on. Would be a waste on a car with manifolds. Have not even checked the dates, but not likely a match for my block, or I wouldn't have had all that work done to them.

Sorry for the long response.
