JJB,
Are they both giving you trouble..?? If you have the hex bolt removed that Firecat Pilot mentioned, try tapping on them lightly with a rubber mallet while pulling up on them....

Are you going to have problems with the track/studs contacting that setup? Isn't that area on both sides of the center rib used for track/stud clearance? Even if it doesn't hit the heat exchanger itself, I am pretty sure that the track hits the center rib. I don't know how the track is going to like a big void in that rib when it decides to hit it. Of course you could run the track soo tight you don't have to worry about it, I guess. Just curious, not bashing. It looks like a neat remedy for cooling issues.

When converting heads to be used for trail use, do they shave them down ? Or are the trail heads thicker than the race heads

SickNasty04F6,
The reason people are changed/machining the stock heads is that the compression needs to be lowered from stock form on the 04/05 440 SnoPro's to run pump(92-93 octane) fuel instead of 110 octane race fuel which is what the stock heads are designed for.

snoprochris16,
When machining the stock 04/05 440 SnoPro head(s) for pump fuel it is the "dome" area of the head needs to be machined/opened up to lower the compression ratio.
