BBB Valves
Hi, I fit Bosa Brothers Valves (BBB), they are made in Argentina. (SuperTech)
I use their Inconel EX and the intake a Blank Nitrate OR ??? for lower weight.
I would get the Springs, CHE's, and ???
I SHIP USPS International POR. (one shipment with low Duty costs)
What country ?

Valve Springs, Valves, etc.
Hi, check around most EFI guys (AUS) know that I provide the IGN-1A Ignition Coil.
They should give you a report about PanteraEFI.com
I would use a Flat Rate Box (Marine Diesel) items for NO duty.
I would fit PSI-1511 ML Valve Springs.
You need to state "Boost", RPM, expected HP, Valve Lift, AND MORE ?
Thus fill the shipment box to MAX Weight.

CHE + Valves + Timing Set
Hi R8, OK, the valve box could be "weighted" with the CHE Rocker Trunion kit.
I would Time-Sert "rose bud" the head rocker bolt locations.
I would fit top quality rocker arm bolts.
I would include a valve seal request.
Remember the cylinder pressure is great with a Turbo AND your chosen EX cam lobe opening timing event will cause greater pressure on the rocker arm than a N/A EX rocker.
Do you have a Timing Chain set ?

GM LS engine = ONE TIME ONLY
Hi R8, the GM LS engine was designed to be assembled ONCE.
DO your self some good.
When you lose a rocker, you lose the Cam and Lifter unless you fit the OEM Tray.
