Message: <blockquote data-quote="dan filipi" data-source="post: 24579" data-attributes="member: 54">I was talking on the phone with MSGT-R about cam profiles, lifts and whatnot which got me out to the garage after to compare the 1200 cam with the older cam.Comparing the rockers and cam holders I then had an idea "how hard would it be to put this 1200 cam holder on an 1100 head?" (The 1200 has hydraulic lash adjusters.)Well the answer to the little voice in my head was "not very easy man but the gains could be worth the effort".No more lash adjustment and matched rockers to my already installed 1200 cams.It looks like all the bolt holes line up, the 1200 cam holder sits right down onto an 1100 head with the cam in place. The most apparent challenge would be oil delivery. 1200 head has a flange arrangement on the head to deliver oil to the journals and adjusters. That little problem would have to be sorted out.If I had a way to close off the cam holder flange I could easily tap in a couple fittings to distribute oil.Hmmm.........Why even consider this?Well the intake and exhaust ports are considerably larger than the on the 1200 head.It's all about performance gains.And there has got to be a reason for 200+ psi on the right cylinders but only 160 on the left. May be due to the rockers.</blockquote>
