Hi
I am in the process of collecting the required parts to start my 1000-1200whp build and was wondering if I need +1mm valves or should I stick to stock size? and why?
I am sticking to 3.8l with 10:1 compression.
I have no plans to go over 1200whp, in fact it will always be 1000whp on pump gas except for some events maybe twice a year where I will use race gas and go for something close to 1200whp.

Hello,
Looking for the following parts for a 1000-1200whp build.
Used:
- Turbo kit capable of 1000whp on pump gas (ETS, AMS, BL).
- ID1700 injectors.
New:
- Tomei 274 cam shafts (or similar)
- Ferrea springs
- Ferrea retainers
- Ferrea +1 valves
Do I require Ferrea spring seat locators, valve locks and valve guides or OEM can be used? If required then I am also looking for those.
