bigweav81 Posted March 1, 2016 Report Share Posted March 1, 2016 Slightly bent stud? Maybe those niche cylinders stud holes weren't machined correctly to be aligned. How far off is it...........rubber mallet lol. sent from yo mammy house. Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted March 1, 2016 Report Share Posted March 1, 2016 Are you torquing the cylinders then trying to install the head? If so, it's usually easier and better to leave the jugs loose and step torque the head to the cylinders in OEM sequence, then torque the cylinders after. It's a simple change in procedure that can make life much easier. Quote Link to comment Share on other sites More sharing options...

registered user Posted March 1, 2016 Report Share Posted March 1, 2016 this is just me but I would do a dry run. make sure the cylinders go down easily on the cases with dowels installed. if not you may need to use some sand paper or dremel in the cylinder holes because the machining is likely off a bit. you don't want to have to beat them on. next make sure the head goes on easily. there should be plenty of slop cast into the head holes for this. if it wont go on easily then I would suspect again the cylinder studs have bad machining. may need to ream the head holes slightly. beat it on with a mallet if you want but I wouldn't. after your done you may want to take a look and see if the combustion chamber is still mostly centered over the bore with no large protrusions.

Bennett131 Posted March 1, 2016 Report Share Posted March 1, 2016 That ^^^ ive had to do that with oem cylinders in the past. Quote Link to comment Share on other sites More sharing options...
ernesto Posted March 1, 2016 Author Report Share Posted March 1, 2016 the real issue is that the upper cyl studs won't fit in the head cover holes , the only way to get the cover is by hammer and i don't want to do it in the past the head cover will fit by hand easily , with these new niche cyl the cover won't go easily 1 Quote Link to comment Share on other sites More sharing options...
