Promaxx shocker 240

[ssyb19]

Hello all, I am looking at some head options for the 440 I’m building. Does anyone have any experience with these Promaxx Shocker 240 heads? Can’t seem to find much information on them anywhere, but I like the price of them compared to the TF 240’s. I would have them checked at a shop, but just looking for any input as far as quality and actual performance before I drop 2300. Thanks!

Spend the extra money.The trick flows are proven and work. Mine needed nothing out of the box and they were checked by the engine builder. $$$ is always a consideration but I would rather know it will work and perform.That is worth something.

The Promaxx may be just fine but is it worth the risk?
