Will a set of 1.6 roller rockers work witht he stock springs? im gonan be doing valve stem seals and figured I might as well upgrade.
Also what rockers would I need? Obviously self algining but are they the 3/8ths ones? Also if i should need new springs what do u recomend?

thanks

 

Stock would be 3/8's and everyone has their own opinion on what ones are best. How many miles are on this motor? I would strongly suggest looking at another set of new springs and changing those out at the same time as your seals. You will be amazed at how well your motor will run with a fresh set of springs. Look for ones compatable with how much lift your cam is going to make with the 1.6 rockers on. Hope this helps a little.

 

the engine has 140K on it but it has excelent compresion so im not gonan tear it down just yet. What is the lift of the stock cam?

 

.404/.415 203/207 114.5. you dont need to tear down the motor to replace the springs. and with that many miles on your motor it would do some good.

 

I was told by someone that I might have to machine the heads so the pushrods will clear? is this true? never heard of that.

 

no, not at all. get comp cams 981 springs. there a drop in replacement spring.and they easly handle the lift with the 1.6RR. http://store.summitracing.com/egnsea...s=false&N=+115

are you fimilar with changing your spring?

 

no not on a car, I have done a few 4stroke atvs. Looks pretty simple though. i just gotta find the tools.

 

im buying 981's will the stock studs pull out with a .500 lift roller cam

 

no, they'll be fine. if you add anymore lift i would get them, but you should be fine with that.

 

Do you know witch stem seals I should use? maybe a part number?
Any type of rockers better than others? any suggestions?
and last Will the stock valve covers fit?



thanks this fourm is a life saver.

 

and one more thing, will the stock pushrods be ok?

 

yes the push rods will be fine as your vavle covers. i dont know the part # for the vavle seals. you could do a engine seach on summit's site. any RR will be ok as long as there self alining.

 

Awsome, thanks alot does anyone know if the stock valve covers are aluminum or steel? And should I get new retainers and shims?? Man i never new there was so much stuff just with valve springs
