These guy's that are complainng already have an alternative head in the World Product's 4360 & 4361 they have nothing to complain about . All of the World Product's head's that I have worked on also have a better Ex short turn radius so maybe they won't need as much welding on the ex side maybe not any . I have not worked on this exact part number , but I have worked on a lot of SR Torquer's and Sportsman 200's and they have a lot better short turn radius than a 441 or 041 . If I ever get my car back together it is a 350 255 Chevy . There is no reason for an Aluminum head on that combination . Like I said earlier I don't want to see anybodies combination made obsolete just keep the replacement head as close to stock as possible and only use Aluminum as a last resort . I agree the exhaust port on the 401 Chevy head is a joke it is not even close to a 840 or 291 . Also I was told that the small block Ford Aluminum head's get a 10 H.P. hit .

The 441 castings (255 HP and 250 HP 2 barrel) are getting harder and harder to find for someone just starting and the price is getting higher. Unless someone already has a stock pile of these castings its not an easy find. They were only cast for one year and it proved to be one of the most popular combinations besides the 350/300 so they were pretty well used up.
