Is this engine builder nuts?

My LA head swap to EQ Magnums on my stock 318 completed last year went like this.
I searched as much as I could to find any issues or downsides to the swap. My costs were:

EQ Magnum Heads w/LA Intake Bolt Pattern $850 (Delivered)
Magnum Rocker Arm set P4876050 $ 94
ARP Magnum Head Bolts 144-3605 $ 89
Summit 7.650" Pushrods (5/16) $100
Mr Gasket Head Gaskets (.028) 2 $ 44
Valve Cover Gaskets $ 20
MP Valve Covers $200
Valve Cove Grommets $ 12
Studs for Valve Covers $ 8
Performer Intake Used $100
Intake Gasket Set $ 20
Plug Wires $ 31
Comp Cam Kit (w/oil thru lifters) $194

I didn't total the costs because you may be able to horse trade or find cheaper prices. Most of the pieces came from Summit Racing. hope this helps.
