Did they ever make a 305 with double hump heads? I ask this because my 305 has them. As far as I know they havent been changed by anybody. I saw this when I put my cam, lifters, and timing chain on. Still had the old chain with the plastic teeth which gives me more reason to believe the heads where never changed since those are performance heads. Car is a 78 buick regal.
305 With Double Hump Heads?

Hmmm.... I have a 78 Regal with a 305 in it.. I wonder if mine has them. How would I tell if I have them or not?
Ok, Thanks. I'll have to go and check when I have the time and when it warms up a little. Oh, And I just looked at your pics, What is the gauge that is on the right side of the speedo? It looks like a clock or something, I ask because my Regal just has a blank piece of metal there with some black lines going in a circle..
No. No 305 came with double hump heads from the factory. Dbl humps were produced in the 60s. Not sure when they ended, but it was long before 305 were produced. All dbl hump heads that i have seen lack accesory holes that all later heads have.
I know what 305 heads ur talking about. My old factory 305 monza had the same ones on it. They have double humps on them, but they are different. They are pointed humps, not the rounded ones like the good heads have.
The heads in question are just basic stock 305 heads.
