Valve train, Information Options

[sjhenry1075]

Hey everyone,

I apologize if this is common knowledge, I am just trying to learn my one thing for the day.

So I am building a 2056 and I just need a little more information regarding rockers/swivel foot adjusters, 8mm vs 10mm adjusting screws, etc..

I currently have a stock 1.7 that came with my 71, but I am also building a 2056 that will have dual 40 IDF's, 86a cam, and 2.0 heads with 44/38 valves.

I keep reading about using 1.7 rockers. Are they referring to the rockers on 1.7 engines? What is the benefit to using swivel foot adjusters? 911 adjusters?

I am really trying to learn as much as possible about these engines and each component.

I was in the opinion that the new SS valves are not has hard as the hardened Rocker tips on both the 1.7 (8mm)and 2.0 10(mm)rocker arms
The 911 swivel rockers and be easily fitted to the 1.7 rocker shaft with a few machined cuts and will reduce the wear to the valves. More Important with higher lift cams. These 911 swivels are a Few $$ more than the after market ones but have YEARS or dependable history.
After makers are now avaialbe in 8mm and 10mm for 1.7 and 2.0 shafts and the feed back has been pretty good. So either should be ok
