Inliners International Forums General Discussion Hi Performance Help needed to change 4 piles into 1

Water heat for the Firebird turbo plenum, can I take water from thermostat housing below the thermostat and return it to the 1/2" outlet on the head between #1 & #2 cylinders? All of my heads don't have that hole but two do. Also oil line to turbo, if I run a 1/4" line from the oil pressure port on the passenger side and use a fitting in that line for the pressure sender will that rob oil pressure from the bottom end? And last for today,Will I get a good enough temp reading if I put the sender in the water jacket of the plenum, or should it be nearer to the thermostat? Thanks!
