I don't have the budget right now to go with a full roller setup so I wondering if I can use a flat tappet in the mean while. Thanks

Thanks If the seated pressure gets up higher than 130lbs@1.80" installed height, the cam stands a good chance of getting smoked (unless your running an exotic lifter like a schubeck)

It's probably 2 springs and a damper but that would still be a bit much for most flat tappet cams. Better to get the springs recommended by the cam manu and change them. -Bob
