These right her do it RIGHT! when it comes to sealing down your valve covers on a GM Crate 350! I haven’t seen any oil leak since these babies have been on! Make sure to buy 2 sets to do your whole engine! Very good quality to keep from bending! I recommend to anyone with a 350 engine! These are legit! Thanks Spectre for doing it right!!!

Fits good on stock sbc 350 valve covers. Only 4 to a pack. You will need to order two packs for both valve covers.

Significantly less than brand names (60-80% less). Works perfect and helped eliminate valve cover oil seepage. To be fair, I have name brand VC clamps that have a better finish for ‘show’ car; but both work the same, and there is not 70% less shine on the Spectre product

I installed these on BB Ford FE 390 on the stock Thunderbird valve covers and they fit perfectly allowing valve covers to seal up better they look pretty good to.

The finish looks great, the fit is tight, and the quality metal keeps everything sealed up without a hitch. It’s got that spectre-cular combo of strength and shine that makes any engine bay look a little more rev-ined.
For the price, it’s a torque-notch above the rest — durable, stylish, and dependable. If you want your valve covers to stay put and your setup to look the part, this clamp is the real deal under the seal!

Worked perfectly on my 1984 f250 with the 460 engine, high quality and spread out the clamping force nicely
