For you guys that had rocker arm flying off issues on the SR, you know that Nissan revised this part and now has a deeper bowl on the rocker arm that makes it less prone to falling off and there are 3 different type of HLVA's and one of them performs alot better than the rest and is less prone to valve float, the newer style rocker arms shoudl be on all 98 and above DET's and the better HVLA's i believe come from the FWD roller rocker sr20 but im not sure I have to reverify that again.
