No manufacture currently stocks anything for these heads.
BUT YA CAN TRY CRANE
They designed the 3.4 factory cam & the factory upgrade to the heads.
BEST YA CAN DO
New guides
3 angle valve job
CLEAN the back sides of the valve & POLISH the stem at tulip area
Clean out flow areas as much as ya want.
Be careful not to hit water & these heads are decent already, so not to much here
Springs, new call Crane
Roller TIPPED 1.52 or 1.6 IF ya keep the factory 2.8/3.1 cam
Fiero Valve Covers
Better effort is put into 3.4 heads.
Go get the GM Performance parts book to exactly find out why.
It costs measly $6!! & ANY GM dealer should stock it
PS cost this "job" out.
Free heads cost ya in the end, too.
