Valve Guide Liner kit- ...save a lot of money, do it yourself. Price $225 post paid in US. K-LINE 3/8 broaches, and complete kit like new with instructions. COST $350 also with about 100 liners. air driver, flex 1/2" driver for drilling pilot hole in heads. Well over $400 my cost for all. Enough to do a pile of Buick heads.
Why pay $10 per guide when you can do it yourself and save $160 on one set of heads. Thats $320 on just two sets.
