i've been doing a lot of reading and researching on these 2. i have came across the company Vee Two. i've on heard a few things about the slowly dwindling company, but were all good. i'm interested in picking up a set of the race cams with their 43mm intake valve. they mentioned it's required to use their valve. it that a true statement? also wanted to get the adjustable cam pulley. i figured for all that it'll be a little less than $600. i know i could do pistons and probably get a more of a gain, but i was thinking this way. pistons will probably be around for awhile, and picking up these engine are now very far and few between now. what are you guys thinking?
