Tomei solid lifter : still noisy ?

[Isofouet]

Hi,

I installed some tomei solid lifters on my SR20, which has tomei procams 260°
The rockers have been machined as required

I check valve tolerances, made a reshim, and the head is still noisy

I use 300V, 15W50, when the oil is cold, the engine is somehow quiet, but after the oil has warm-up, it's almost as noisy as a failed hydraulic lifter.

Do you have any idea why it's so noisy ? Is it normal with solid lifters ?

Thanks

Someone with more experiece could answer this but I always thought noise was an unfortunate side-effect of solid lifters, not 100% sure though
