89 top end kit?

So Im trying to decide. Edelbrock is $1700 but doesnt include EFI
intake. Trick Flow is $2400 and is the winner cause they include push
rods, EFI intake AND roller rockers! BUT they dont include the roller
lifters for the roller cam. Is that because its ok to reuse stock
roller lifters with the new cam? Also will the twisted wedge heads
work with stock pistons? That would be my first question to the phone
tech.

Anybody have first hand knowledge of this stuff?

Thanks
