Just got my 1600 dp head drilled and tapped for a new stud and when I pulled the other one, I have what appears to be a small teeny tiny CRACK. :shock:      
Mama always told me to stay off the crack, I guess I need a new head....(must be read in the voice of Forrest Gump for full effect....)

I guess I want a set of them as I am nervous about mixing worn and newer heads.  I am going to buy a new set if I have to, but would be open to a gently used set where someone has "upgraded" their motor.

I am not interested in sets where the valves have to be installed or lapped.  I want to just bolt and go.  Let me know what you have.
If anyone has any preferences as to which ones to buy, let me know as well.

I need to stay with a stock set up as I am running an Autostick and the extra HP would just be lost on the little teeny tiny clutch that I have...
Thanks,
KC

I appreciate it.
A local triangle person has said he has some single port heads / intake.
Is it going to be better to go the single port rout and get a new carb, or is it going to be better to get new / rebuilt heads and just keep the "new" carb that has been on the car for about 3 years.

I like single port engines. They seem to have a little more low end torque. Two things to do if you go the single port route. The intake will have to have a vacumn port like your duel intake has. You can try to locate a '68-70 auto-stick intake or '70 type-2(bus) intake or you can cut and weld a port into any single port manuel shift intake '66-'70 type-1.
      You will also have to change the two upper, inner cly. head studs on each side of the case. They have to be the same lenght as the upper,outer studs. I hope I didn't confuse you there. You can use a PICT-3 or a 30-31 carb without an adapter. :?
      Like Scott said, single ports are very reliable. Thats what is going on my Allison
