Pro Comp heads are installed.

I got the pro comp heads and intake, carb, and rockers installed on my 340... finally. The only problem I ran into was that the rockers didn't clear the valve springs. At all. I had to remove a lot of material from them. Which required removing the entire rockers and shafts multiple times to check clearances. The process took me two days just to get them to fit. I haven't driven the car yet because the valves aren't adjusted perfectly yet. However, let me say this car sounds insane now. The boosted compression and air gap style intake makes this car sound like a super stocker. The pro comp carb actually feels crisp when I push the throttle. There isn't really a combustion chamber to speak of. So, I guess that is why this thing sounds so nuts. The intake runners are huge compared to the x-heads. Overall, I feel like the $1275 I spent was worth it. I feel like a snob now because I scoff at the thought of stock parts. In fact I am selling my x-heads with adjustable rockers because I am never going back.
