have a 1999 Z mods are headers/exhaust, 3000 stall, lid 9 inch w/4.11's

just bought a MS3 cam and lookin for heads. what would be the pro/cons on these 2 pair or what would you recommend. Plan on goin with a bigger cube motor later on.

GTP stage 2

5.3 Stage 2

thanks ~Jason

 

You will want larger heads when going with the big cube motor, small runners like for a 346 will choke a 400+ Ci motor.

 

yes, i know that. will the bigger heads really hurt the stock cubes? it will be next year before i think on the bigger cubed motor.
