Eddy heads. Can I/Should i...?

Tim,
What view is that? As for the eddy's on a low compression engine I wouldn't do it, but thats just me. Maybe thats why Alans friend only ran 12.30's with them. The Eddy's don't have the port velocity that they think, so they have a dual quench chamber, but the chambers don't control how the air flow moves through the ports. Even the best chambers cant help sluggish ports. 170 cc port runners and large valves on low compression engines and mild cams to me would be a serious mismatch of parts. A smaller runner head with the same amount of air flow with a smaller intake valve will produce much better results than a pretty set of heads. Eddy's flow 240 or just a bit more stock and a set of 360 heads flow in the 220 range with a bowl cut, but the 360 heads have 1.88 valves and the Eddy's have 2.02 valves and the 360 heads are 150-152 cc's not 170 cc's. So even if the port is smaller and the air flow is less the velocity will be higher and the speed at which the cylinder will be filled will be nearly half again as much, and this helps compression, producing a tighter pack of the air fuel charge, making more HP and Tq..

A good 360 engine doesn't need more than 168 cc's of port volume and for street and mild racing 155-158 cc's. And flow in the 220-240 range, flow of 230 cfm's will make or be capiable of making well over 500 HP. Also too the smaller runners help fuel economy with the ports being more efficient. A engine is a efficeintcy pump, the more efficient it is the better it will operate. Too large of port volume, intake, or cam and efficientcy go's out the window.

It's really up to you as to what you want to do, and you won't be happy unless you do what you want and not what everyone else want's you to do. But IMO there are much better heads out there than the Edelbrocks. You'll pay more for them but you'll have more when your done also.
