Hi Dalamr/all,
I forgot what thread it was in but I think you mentioned a gentleman on this site who had npi heads and did a manifold swap and had Houston Performance blower cams. I would like to hear from him, I need to know what springs/retainers he used. Steve at HP said the stock npi springs would not work, and that PI springs also would not give the proper install height and pressure. I really,really want to do this, so any help would be much appreciated.
Thanks
