Most Dyno shops have Dyno headers. I'm sure some don't have Mopar headers at all. For ease of hooking up to the Dyno they use headers.Manifolds would be another setup and ain't nobody got time for that.As well as most all race engines and hot street engines run headers.May not be the same tubes...

It depends on your gear,driving habits, among other things. If you have a football field sized torque curve stall is less important unless you are drag racing. Then shift recovery plays a role. A small engine with lower torque at lower rpms will want/need more stall to keep the cam from falling...

So when are these going on a 318 build !!!!!!?

My guesses are usually off but here goes 14.78

:rofl:

We did that on my Duster with RB block, 2" Tti, and trick flow heads.

FOR SALE - Edelbrock Victor 440 heads freshly rebuilt and matching offset roller rockers $2000 in central Texas FOR SALE - trickflow 270 head package Now $3900

I think this one came after the previous one listed. At some point they dropped the "hemi" grind from advertising IIRC.

Any of the heads is a better choice than sinking money into old iron heads. A better valve job and a little port work is more than 20 HP as well as the other benefits of aluminum. 20 HP is still 20 HP and with a bigger cam the difference grows.

The closest quarter mile to me closed this year as the land it and the dirt track were on sold to developers. Now Rockingham is probably the closest and doubt I will drive that far and I don't own a trailer. I always argued my c bodies needed the whole quarter to stretch their legs lol.

If you don't need the money then keep it. Vacation home(sort of),weekend getaway? Remodel the upstairs for living and leave the apartment as a garage until you decide you don't need or want it. Vacation rental? Bed and breakfast on the river? Rental for small parties,weddings,etc in the garage...

I loved the 280-474 cam in the big blocks. I loved the 272-455 as well. With a little more compression,gear,and converter the 474 comes to life. The 455 was great for a heavier car with 3.23 gears. I don't see why they wouldn't perform the same in small blocks.

Buy them! How can you lose money at that price? Aluminum heads are more tolerant than steel heads,thicker head gasket, and your timing curve can be slowed as well. You won't find a deal anywhere near that even if you have some extra costs getting them installed and setup.
