Re: can i run a 1.8 rocker arm w/ a tr224cam I'll let you know in a months..... 
With my TR224/224 112 LSA, I have in excess of 0.100” p-to-v clearance so the extra 0.033” lift won’t cause me any real problem (might put me in the 0.070” range but that’s still more than the 0.060” clearance that Schneider calls for on their cams.....)
With my 0.020” mill and large valves, I can't go large enough on duration (probably get a TR227/224 in.....MIGHT get a TR230/224......) to make enough HP that a cam swap would be worth the cost/effort......
I have Comp 987 duel springs so I'm good to well over the estimated 0.596" lift I'll be getting....
Finally, short duration/high lift tends to keep low RPM drivability the same (good torque) but really lets the top end open up (acts kind of like a solid roller cam)......
