I got that post out of the for sale part on the web site and posted it in this part because i didnt know gemini engines came out with alloy rockers... sorry man

I seems that G180's had cast alloy rockers, and the G161's had cast iron rockers. It might be a model thing though, with a certain model (TF or TG) all having cast alloy rockers, and 1800's of the same year had them too.

The year of the air pump, whenever that was, early to mid eighties.

Really??? whats your thoughts on them Ben??? do they make much of a difference??? is there a steel insert for the cam lobs??

I guess they are lighter, but I haven't weighed them, they are slightly larger. I use them in my engine because I thought they would be lighter.

They have a hardenned steel plate that rubs on the cam lobes.

Damm that shit's wacked!!! all this time fucking around with gemini engines i never seen an alloy rocker in one yet... I best get onto it. Do rodeo ones fit you think?

alloy rockers are trash. they wear to quickly and make annoying tappety noises.

a mate of mine who is an engine reconditioner, said every rodeo that he has built, he has pulled the alloy rockers out and put standard gemini ones in. hasnt had any problems with wear.

Been running them ever since this post and never had a problem
Had to modify the rocker stafts a bit tho to make them work well.

I've been running alloy rockers on my race car for years they are not a problem , They have better wear pads than stock cast rockers .. Early rockers were just case hardened and would wear out and in turn wear out the cam..later they came out with decent wear pads on the cast versions and again you would find that they would wear on the rocker shafts ..Finally the alloy rocker came out on the g180 , g200 , 4ze1 etc all interchangeable they are the way to go .. Never broken one , even with heavy valve springs...really the only way you will break one is if a piston is hitting a valve...better to break a rocker than fuck a piston eh ??
