should pushrod length be rechecked if im upgrading from 1.5 to 1.6 RRs ?
I know that cylinder heads, CH gasket, and bock deck hight is what indicates the pushrod length, but what about RRs? im just curious cuz im goin to rev high with my new build and i dont want to take any chances ! :)

sometimes you can get away with the same length but it's always good to check them out anyway. takes only minutes to do. i have 1.6/1.5 and my pushrods are the same length.

the only thing i would wanna keep an eye on is when you add lift via the rockers is that your springs can handle it.
