hi just want to know if many people try the s1x with roller rockers i searched and what i found is many times you need to modify the head for 1.7 and 1.8 roller rockers but i have intense racing stage 3 heads and can go up to .600 lift. i have many mods like gen v intercooler n* tb is3 heads .... do i will have big gain with the 1.7 or 1.8 vs 1.6 roller rockers does it has poeple try the different combo ????? i have a fiero and want some power but dont want to loose all the low rpm range. many thanks all
Technically a 1.8 roller would give you more valve at low cam lift areas than stock would, but I am not sure if it would do anything to change the power curve as LSA and duration is not going to change.
why all say stock and not 1.6 roller rockers i tought it was better the roller because the roller will less damage the valve guide and valve stem tips no ?????
