Hopefully the last question on heads..
 

O.k. the day is coming near for the heads purchase. Gotta clarify a few things to make sure I screw up. On trick flows twisted wedges there are 2. One for stud mount rockers and one for stud mount rockers w/O-ring groove. Which one do i need? My car is a 94 stock block, so which way do I steer? I know with these heads, I have to buy additional parts(you know, pushrods and extruded rockers[saw it in Summit]) which makes them a bit more than Edeleborck's IF edel's don't need any more parts. Do Edel's need additional parts to bolt them on? Thanx again...Oh yea speaking of Edelbrock, anyone try the inertia shocks?

My edelbrock heads needed nothing you can reuse your rockers and pushrods I opted to get roller rockers and bought new pushrods cause there cheap and its just cheap insurance that your not putting in a bent one.
