Low deck hemi

Anyone done a low deck hemi?

I have a set of Stage V conversion heads and am planning a 500ci low deck motor for my 69 GT. I know I will have to build an intake, but was going to do that anyway as it will be EFI and boosted.

Can you think of any reason I couldn't use the heads on a low deck?

Thanks!

The low decks were pioneered in the early 80`s for prostock and comp dragster applications. At the time hemi blocks were drying up and heads were going for a premium (enter stg.5 conversion heads) . The blocks had the extra bosses furnace welded in so original gen II heads would fit . The prostock effort didn`t get that far unfortunately (see Charlie Maluke) But Dave Koffel and Wally Dyck held the A/Dragster records for years. The engine was / kind of high dollar to build and became obsolete when better big block heads came out (Zeeker / B1 / Indy ) .
Neat project motor , but will be a little $$$ because of all the custom stuff to be fabbed and then made to work, the kind of motor they would build for Engine Masters . If you`ve got access to a dyno for testing parts ....great. You do know the stg 5 heads are a bit of a compromise to fit the B/RB platform , right? In the end a set of Indy`s or your choice of big block heads might be less headaches .
A low block hemi will scream and make big power , but with today`s wedge heads will probably pale in comparison .
