Replacement Clutch

looking for opinions on new clutch. Stock 340 with just headers. (around300 HP). i'm thinking of Brewers, they recommend taking the over center spring out? I'm sure there are members with experience here. thanks for any opinions.

Hello bballfan1,
Installed the LUK 05029 (Rock Auto) clutch into stock ish (small cam) 73 340 4 sp with 321 gears.
Did not remove over center spring.
Can drive in rush hour traffic without killing the left leg...
Been in 2 years and still going strong.
Resurfaced Flywheel and polished front input shaft housing for Release Bearing.
Stay safe...
Happy Mopar :)
Arron.
