Hi Adam, If your using the original eta head ie 200 casting, and you want to use a better cam than the eta one that has only four journals, you need to drill the head to match the oil feed for the 2.0 2.5 or shrick etc cams that have 7 journals, but if your using the 2.0 head 731 casting then no need, you can put any cam in the 731 the oil feeds are allready there, if anybody is interested i have a head for sale that ive been experimenting with and when finished should be the daddy of all 2.7s using eta pistons, it has valve seats opened up to accept 2.5 valves, ports opened up to similar size as 2.5 and flowed, this will be a stormer i recon when finished but ive no time at the moment, so all it needs to finish is slight welding on water jacket then a skim, valves cut into head, and bingo proper compression matching combustion chambers and 2.5 vales and port sizes, whooooooooooo, let me know anybody that wants it Ԛ£50 to clear, cheers Dave
