Can i use LT4 valve springs with the cc305???

 

You'd be OK if you were running 1.5 rocker arms, but with 1.6 rockers the CC305 has .544" lift which is too much for the LT4 springs. I'd look in to some other options. The Crane 10308 is a good spring for the cc305.

 

I wouldn't chance it. Coil bind is a very bad thing. Go with either the Crane kit or some CC918 springs.

 

yea im jus goin to keep tha 1.5 rockers....would it be alright to drive for a lil while untill i got a mail order tune??
