    I have a pair of heads that have 041 as the last 3 numbers in the casting number. They are a semi-closed chamber head with 1.94 valves. I believe them to be originally off a 327 from the mid '60's.

    I have access to put a solid lifter cam in a .030 over 327 I have. I have some other things collected for this motor including 11:1 pistons, an Erson gear drive and roller rockers. I'd like to use these 041 heads.

    I take it, I probably should have screw in studs installed? What about hardened seats?

    041s are '68 - '70 350 heads. They have 64cc chambers, and are the heads that were used on the 300hp 350s of that era. They are a good head, and a good heavy casting. If you are building a motor that you want to last for a long time, you should go for the hardened seats. As usual, a set of Vortecs will outperform those heads, so weigh how much money you will have to put into reconditioning those heads against that swap.

    I also have a pair of the camel hump heads, not the full closed chamber, but semi closed and with the accessory holes. They are just the bare casting, no valves or anything. I wonder if I should just have them gone through the way I want them instead of tearing the 041's apart.

    Those would probably be pretty similar to the 041s, both are likely 64cc.

    They would basically be the same as the 041's. The double humps you are talking about are probably 186's or 187's. They are all good heads. I would use the 041's since they are complete.
