Warwick;

I do not know squat about proaction heads,but I would definetly now bore a 351-W block more than .040.......I have heard of people going .060 and not having any trouble,but I have heard of twice that many going .060 and having trouble...........I'd try to find another block that would go .030 or .040......

Just my .02 cents............
