I have here a picture of a Sun racing valve spring with a size of 2.8 mm compare with the stock, 2.5 mm with same length of 47 mm. My question po, will this be compatible with a RCDI, 62 mm chrome bore w/ semi dome forged piston & a cam shaft of a 5.7 lift? Any comments pls. before I install this? Or does anyone used this set up? T.I.A.
