I was wondering if this can run this on older gills with silent choice risers the risers in the picture came with it, but they guy who has this would like to go to silent choice

what do you have for exhaust

sorry bout that i updated my post. but cant seem to load pictures tonight

Go roller and skip the flat tappet stuff. I just tore down an engine that I bought to rebuild, whoever first rebuilt it did a $hitty job, anyway, they used a flat tappet cam and 5 of the lifters when flat and took out the cam and sent metal flakes through out the entire engine. If you do some searching this is a very common problem, even with professional engine builders. Spend the extra money now or pay a lot later. I almost went the flat tappet route on my current builds but I'm glad I was talked out of it.

its already in the motor and has about 20-30 hrs on it. it runs real good and seemed to work well in my 27' baja. A friend bought the motor from me and was thinking of putting on a silent choice system thats why im asking

I would not run silent choice with a cam that has a 110* lob sep. It needs long risers for sure that mix water far back.

heres pics of motor and exhaust its a 30 over 454 with mini domes 830 cfm holley and 188 heads

Silent choice will not fit with those risers anyway.
