Some light reading on the subject:

For something that's a daily driver or mildly used for towing, I'd use iron heads and compute your compression in the 8.5-9.0 range. Don't go crazy with compression if you are towing otherwise it will be more difficult to tune (ie: you may have to sacrifice timing). Don't forget you want a good torque band, and if it comes in low, that means you can cruise with it at lower RPMs even with a heavy load. You could probably use aluminum heads on a tow vehicle, but I personally wouldn't. |
At the advice of the Captain and yourself I did a little reading on dynamic compression. I think my little brain almost exploded. I do get the basics of it though. Ill be trying to keep my static around 8.5 which I think it may have been close to stock.
Just for learning sake though, you and Steve have advised against aluminum heads for a towing engine or DD. Id like to know why. Iron heads are far more budget friendly to me so I like the advice but my curiosity is killing me.
Lastly, Steve I noticed that you're running a Straub cam in your stroker. How do you like it? All that Ive heard is good things about his custom cams. How is it working for you?
