Do diffrent heads require diffrent length pushrods?
I'm going with either Edelbrock perf. or AFR 165's, Both of which claim you can use all stock components, valvetrain too if pedestal versions are used.
Now, what about pushrods? If the spring installed height is not the same as stock than stock length p-rods won't work will they.
I would assume I'd need shorter p-rods, as stock springs bind at like .509 lift and both aluminum heads above will take .575"&.550",respectivley, so wouldn't they're spring installed heights be taller?
I've never changed heads but I know all this stuff is readily available as I'm the only one left running E7's!! Any advice or opinions on any of this rebuild plan is greatly appriecieted.
New rebuild under way, 306, Forged pistons, Eagle rods, stock crank, Typhoon intake ('cause I got one), 65mm T.B., 70mm "cobra" air meter ('cause I got 'em), AFR 165 heads or Edel. performer's, Trick flow #1 cam (221*/225*@.050 .530/.542 lift W/ my 1.7 RR's).
