Keep the rest of your piping 2.5" for now.
thought it was close enough to stock to work with the cam and not effect, thanks!
is it because 1.9 rocker and the cam grind is too much force on the springs and valvestem?
or it will effect valvefloat and throw the cam off?

reason for wanting them is to be more reliable at higher revs. the intense sx1 package comes with some heavy duty components to handle the power of the cam, but leaves out most noticeably pushrods and rockerarms, is it because our stock rockerarms and pushrods can handle it?
figured moving to a 1.9 ratio will make for a more heavy duty rockerarm than a 1.6, but now looking back on it, it can effect the timing of the valves, and postion of the rockerarm might not be adaquate
up to what RPMs are the stock rockers reliable for?
does the series II L67 come with tip or fulcrum rockers? or are they the same thing?
thanks for all the help and the time its greatly appreciated ,i still need to clarify/research some stuff.
