The GT-40P heads were from the Ford SUV.
Their exhaust ports do not align with the headers used on all other
small-block Ford heads.
A better aluminum head is the GT-40X or GT-40Y, which give much more power &
are available new or used in great numbers for very little money.
They'll also run cooler & take 40lbs off that front-bias Sunbeam front end.
