getting another set of camel humps today, guy has a rebuild set of the 0193 85 year i think, 64cc chambers. they are for fuel injected, can you run on a regular aspirated car or not? they are 50.00 and figure cheap and good compression. not really looking for performance out of them.

They will work but the center intake manifold bolts are at a different angle (centerbolt heads) and they may also have the swirl port design. For a regularly driven vehicle that won't be raced these would be real good low end torque heads.

What's the intake runner, and whats the engine specs your plannin on putting em on?

just planning on a semi stock motor. 9:5 compression with these chambers, a 264 cam, maybe cut the ramp out of these a little if it wont hurt them. stock ram horns, performer intake, hei, and 600 carb on a auto vette. will be for mom and law, and wife occasionally, wont be revved past 5000 and wont see hard use. figure they are made for torque, could be good for around town.

Those heads aren't very good. They are the TBI truck heads, and they are terrible performance heads. They have a huge ramp in the intake ports that, in theory, atomizes fuel better by creating turbulence. In reality, its just a big **cking blockage... sorta like a snot-rocket in your nose actually.

Dark,
You'll only see those heads good for low rpm torque!
Attempting to grind or cut out the intake swirl ramp is futile.
The port design is tapered but has a bad "Dog-leg" and will run out of steam before 4000rpm.
They sometimes crack badly around the seats and near the outer head bolts.
The chambers are another nightmare. They can be cleaned up and smoothed around the spark plug.
Your engine combo would work with these heads but you'll need to re-think the cam. It would be better with a cam of no more than 224 degrees at 0.050" and 112 degrees lobe seperation. Pretty mild!
I would say you're better with a set or S/R Torquers in small chambers or just go Vortec. With Vortec, you'll have torque and performance with decent mileage!
