Alright, right now I'm looking at getting the Holley Stealth Ram manifold and Trickflow 23 degree heads for pre 87 blocks. I have an 88 block with centerbolts now. From what I've read there shouldn't be any problems doing this other then non self aligning rockers and hardened pushrod for use with the guideplates and new valve covers. Just wondering if I'm correct with what I just said. Also is there any problems with sensor mounting locations?
Any responces would be great
Thanks

If you are replacing both the intake and the heads, why worry about how the parts will bolt up to the old heads? Worry about how they bolt up to the TF heads. Are the TF heads pre-87 bolt patterns? is the HSR pre-87 as well? If "Yes" to both of these, then the intake and heads will bolt up fine. As for the rocker arms, TF heads don't need SA rocker arms as they have guide plates.

Thanks I just needed the okay
