I had a spare head rebuilt for my 250. The rebuild included new valves, springs, milling and a 2bbl addition. Tomorrow, I will start the beast. Of course, I also added a header which if the head wasn't removed when I set it in, man that would have been a tough install. I hope the mods gain me an easier car to drive in traffic. I hate the feeling of having to floor the accelerator just to accelerate alittle. I'm also hoping to gain a little fuel economy with a freer breathing engine. I'll let you know. Ken
your fuel mileage should pick up quite a bit as the engine won't be working so hard. keep us informed.
I am back on the road, and didn't get the car completely assembled. I will have it running next month and then post results. Ken
