1.5 rockers are easier?,,,must have missed the memo....Got 1.6 rockers on 3 engines going up and down the track....was no different the setting up 1.5 rockers....LOL
and a fourth engine on the engine stand with 1.6 rockers...
What your missing is what head that is on top or what it could be changed to in addition to that this is a new guy asking the question. If you use the KISS method there will be less variables to contend with.
The possible areas that could interfere with the pushrods, rockers needing grinding for clearance with what spring is it he is useing now??? With what rocker brand????
You post lends itself to an awaiting disaster or did I miss the memo that all rockers fit without mods? With all springs? Without worry of coil bind?
