Used these plugs on angle plug SBC heads to work around headers. Good plugs, good stuff.

4.0 out of 5 stars ACCEL 0576S Shorty Copper Core Spark Plug Are Strong 3/8 Inch Shorter
Reviewed in the United States on October 29, 2022
Almost everyone writes a review on the quality & how well the item functions. This is important, but these spark plugs are bought just as importantly, for creating more room between the spark plug boot & the header tubes of full length Headers !!
These ACCEL'S 0576S Shorty Copper Core Spark Plugs are a strong 3/8 inch shorter than the ACDelco CR-44/45 TS, & close to 1/2 inch shorter than the E3's - E3.42 Spark Plugs for a SBC engine, which I tried also. Both of these ACDelco's & E3's ran good in my SBC, but 3 cylinders needed more clearance help. Anyone that's familiar with the 1955 Chevy Models Bel Air, 210 or 150 (in fact all V8 Tri Fives) with stock frame & CPP Series 500 Power Steering Box, & running long tube headers, You need every 1/16 of an inch you can gain for clearance between cylinder numbers 3, 5 & 8 spark plug boot & header tubes.
I hope these spark plug reference measurements can help with any flavor car you have a fondness for, that's looking for any 1/16" for a clearance problem ??
I'm only giving 4****STARS, because only time will tell if they hold up, if I knew that I'd give them 5*****STARS !!

Worked well on Chevy 350 in a '74 Camaro with Headman Headers. Normal sized plugs would be too close to header and melt the plug cap, assuming you could even fit the plug or a wrench to tighten.

These work amazon in my 72 Gran Torino with a 351 Cleveland. These are noticeably shorter than the stock plugs I pulled out which keeps the sparkplugs wires further from the hot headers. I did not see any performance improvement but they fit and work great.
