spsparky,

What do the indicator's on the ends of your heads look like.

Do they have a rectangle laid flat at the head gasket surface with a big triangle sticking up in the middle of the rectangle???

Or what??? Because they might be a set of 250hp/327 heads or early 300/327 ones that came out before the double hump heads prior to '64.

What's anybody else think, ---- come back if you have one of those casting books, please. pdq67

The 441's are good heads. They came on 4-barrel 350's that were rated at 300hp in 69 and 70. These are decent heads for a low-mid performance build up. The combustion chambers are about 74cc and the intakes are 155cc. They still flow better than someother heads with larger intake runners. I had a set on a 350 and they produced an incredible amount of low end torque. They do take the flat seat plugs so make sure you buy the right ones. Good luck with them.

I have these heads on my 383 and they work great. Have good performance and gas mileage.
