'03 800 REV mod engine questions

[skidoo_rider #1]

I have a '03 ski-doo mod race sled and i was wondering if anyone knows which base gasket is in this sled? Also, when i put on low comp heads, do i have to remove the coolant restrictor in the hose between the bottle and head? thanx

You have to look at the base gasket to find out how thick it is. Should have holes in it to determine which one you have. example 3 holes equals .3mm. Leave the restrictor in.
