Quote: From reading this the main knock seems to be the stock parts aren't really 1.5 while the rollers are 1.6.
Any reason, or maybe its already available, why not have "true" 1.5 or 1.6 stamped parts?
Usually with roller you have a choice between 1.5 and 1.6
Stamped and stock cast adjustble 273 rockers are around 1.43 to 1.45 IIRC?
Running a high lift version of your cam is a way to net out roughly the same as with a 1.5 rocker. Valve doesn't care what ratios it takes to get it to a certain place. If it gets there, it gets there.
