even more questions. should I automatically replace
rocker arms and pushrods?
1964 289 heads have larger valves and 275# springs good for .550 lift.
My current set are not overly worn but I wonder about having stiffer than stock springs.
Also, do roller tip rocker arms really make a difference with temp and/or performance?
Thanks for any advise.
