My question is , is this a good set up or should I look for some other heads? I plan on using the engine/trans in my 46 1/2 ton. I want good profomance with good MPGs. | | | | | Joined: Jun 2004 Posts: 8,597 Riding in the Passing Lane | | Riding in the Passing Lane Joined: Jun 2004 Posts: 8,597 | 305's use heads with small valves as the larger valves will hit the cyl. walls. . You must have small valve heads or someone has ground a recess for them. You may get good performance but you won't get high performance from a 305.

I not looking for high high performance. The 305 seemed like a good choice for good gas milage and good performance. The heads are 1.72/1.50 or 1.84/1.50 valves (8795896). I see alot about 416 305 heads. I wonder if they would be a better choice?

There's a machine shop down in Florida that's selling heads set up that way, with guide plates and all the go-fast goodies for a very reasonable price. I don't remember the name of the place, but they advertise on E Pay all the time. The 283/327 "Power Pack" head with the pyramid-shaped casting identifier on the end of the head also has a 58CC chamber, but the valves are smaller.
