"TBI Heads" weight
How much do the heads from a TBI 305 weigh each?
I took apart my LT1 heads and they weigh about 20lbs. I'm trying to figure out my weight savings from a k-member, LT1, and a few other things

Stripped down an L05 head weighs 46#; the LO3 TBI heads probably weigh the same. Later heads like the L31 head weigh 41#. The info is per this thread.

Fully assembled L98 head = 50lbs each. I'd assume this is VERY similar to any other SBC head.
Bare LT1 head = 19lbs each.
Just about 60lbs weight savings (a bit less when you add weight of LT1 valvetrain). Not too shabby.
I can get an exact weight of an LT1 head with stock valvetrain components tomorrow. Waiting to find time to install them on my 305
