Its time to replace the valvesprings in my daughters 360. Stock 502 heads with a mild hydraulic cam .488 lift. What is a good replacement valvespring? The motor is a dedicated mud racer that sees no street duty. Any suggestions are welcome.
I need to add that I have upgraded to 1.6 alum roller rockers w/3/8 studs already. It might seem like overkill for the mild cam but I have to pull 17" of vacuum at 800 rpm per the class rules. It usually pulls 18" reliably but these springs are old....seems like its time to wake the motor up a bit. Also, will factory style valve covers clear these rockers? Alminum roller tip from Indy.
