Reply to "Aussie vs. 4V Cleveland Heads"

I would go with the 2v heads. 4v are just all out race head designed for high revs and big CID. If you port out the 2v, it will out perform the 4v for most applications. My ported 2v heads flow over 300 cfm which is 20+ cfm more than the 4v heads. The important fact about the 2v head is the fact that they keep the velocity up!!!! Very important when trying to race!!!!
