Hi,
Was just wondering if there would be any issues using roller rockers to suit a injected 304 on a Holden 6 cyl 12 port head.
The roller rockers are Yella Terra's 1.65 ratio designed to suit screw in studs, the head I have here is a blue motor 12 port that has been machined to suit screw in studs.
The cam I plan to be running for the time being is designed to suit 1.5 ratio rockers.
Will I have any issues if I go ahead with using the 1.65 ratio rockers?
Thanks
