Any suggestions on the best process for pulling the left head off a '68 Barracuda with the high performance exhaust manifold with power brakes and power steering? Can I leave the manifold on the exhaust or do I need to drop the exhaust? Thanks

I leaks out the base of the head. the studs can make it alitle harder to get the heads of with the exhaust still there, i have not tried this mysels since everything i own has headers

Will need to split the ex pipe and take off the inside bolts/washers and the nuts/washers off of the front and rear stud then remove the ex manifold. (dont forget to drain the coolant down a bit). If the ex man cannot be totally removed WO r&r ing the ps box then see if it can be moved over enough for you to R&R the head. EDIT the front and rear bolt holes (only) are wet (SB) Last edited by RapidRobert; 09/19/10 10:25 PM. live every 24 hour block of time like it's your last day on earth
