Head porting

hey guys.

i bought the EQ-magnum heads from ebay.. mmmm but they need alot of worke. lets make a tred on porting /how to, ive done some j-heads in my time but this will be the first magnums. please come with some bright ideas and best of all, do anyone provide port guides/templates for these heads. mmmm also there valve guides and seals are bit tall.. and the spring seats dont have room for dubble springs.. i need some new tools cus of the thinner valves my old cuters wont worke..

have anyone done these heads before??
