How much room you need , the last one I done years ago I angle mill the exhaust manifold to move it enough to clear the air conditioning expansion valve, it was a close fit , at the time I had a bridge port and milled 3/4 inch in the front and 1  1/4 in the back , it moved the rear exhaust outlet inside towards the engine 1 1/2 inches just enough to clear , but this was on a 77 pinto  , you may have to install the manifold and set the turbo on the top and eye ball how much you may have too machine off to clear , just an idea , it work on my 77 ,
