just wondering, im soon to purchase a set of roller rockers for my 161 head, and wondering if many others have gone for the option of running a small block chev 1.5 ratio roller rockers?, least you get two spare then... or should i just purchase the general yella terra rockers which are built for these heads...?

Cheers! Blake

I have two sets of Yella Terra Roller Rockers to suit 161/186 I am about to sell. YT5007 (1.5 ratio) - dyno time only, & YT5018 (1.6 ratio) about 500km on them. Both sets in as new condition. Also have 3/8 screw in studs and brand new guide plates - but you don't need these.
