u can get a tube welded on to the intake along its entire length and have the hot water running through it...very simple to do. although i dont think a heated intake is necessary...as far as i know the heated intake is for economy, if u want more power then run it cold....i dont think its too much different with the concept of cold air induction for caberated or fuel injected...so if u go with a header dont worry about anything...if u notice poorer performance, then its no problem to weld on the tub and change the hoses a bit.


got my 78 merc with a 250 I6 and i love it.
