Performer Pontiac heads utilize a D-Port exhaust port configuration for use with standard D-port exhaust systems.

These heads are available in three heart shaped combustion chamber sizes, including 65cc, 72cc and 87cc. The 65cc combustion chambers are as-cast while the 72cc and 87cc chambers are fully CNCd to provide a 9.5:1 compression ratios when used with flat-top pistons. The spark plug has been relocated closer to the exhaust valve for improved performance. These heads are cast with extra thick port walls and a compact port size, making them ideal for CNC and hand parting. Complete heads include guide plats, rocker studs and high quality valvetrain for direct bolt-on application. Head crossover machined for 50-state emissions legal performance. INSTALLATION NOTE: 350 c.i.d. engines may require notching the block for valve clearance. Three head bolt bosses are raised higher than the standard D-port heights and will require head bolt kit #8561 to install these heads.

Super Low Quality/Unacceptable QC
Color: Black, Size: Wheel-6 Panel
I spent probably about an hour putting it together, only to take it right back apart and pack it up to return. The dimples for half the poles were on the wrong side (double and triple checked to make sure they couldn't be spun around. The threaded ends for the wheels were freely spinning on all but 2 wheels, making it impossible to actually tighten them fully. Once it was all put together, the screens could not be folded up to neatly put it aside when not in use. All in all, this was shamefully low quality for the money spent.

Not as tall as anticipated
Color: Black, Size: Wheel-6 Panel
Definitely not 6 feet tall, more like 5 1/2. Very sturdy and the fabric is thick. Works well for what we're using it for.

Easy assemble and not to big!
Color: Black, Size: 132in-Large Metal Base
I bought this because I fo a lot of zoom/teams meetings and work just mandated no false backgrounds (don’t ask) soooo to hide my real home and allow others to roam free while I work I got this. Easy to assemble although you will need some space. I thought I might be to big at 11’ wide as I have a small desk area but actually it’s perfect and could use a couple more panels. Leaves just enough room so I’m not completely cocooned - I can move my chair and get up walk behind chair and exit space. Great deal and tax deductible!
