Nothing like a little controversey to liven the old forum up. Be forewarned that your " back and forth " aint nothing compared to something that will break later on today. As far as aluminum w-heads go, I will voice this prediction. Edelbrock aluminum heads-- aimed toward street market-- $2,000 Bob's heads sell for $3,000 Waldens heads $4,000 to $5,000 ( a guess ) People will now have options as to what head they want to buy for their purpose. Up until recently we have had little option. No matter how you look at it, things are getting better.
