I have a 460 and I currently have steel heads and I'm thinking of changing them out for aluminum heads. Has anyone here ever had any warping problems with them (berkley jet)? Also, can some give me the pro's and con's to changing them out? I have a 23' footer and I'm not going to be out racing or anything, but I would like to add more horsepower for added weight to my boat. Obvioulsy aluminum or steel isn't going to make that difference, but will there be any real difference in the weight of the motor?
Thanks for any and all input.
