Here are some pics of the 1133 next to a regular fel pro graphite. The other pics is the 1133 on the block.

 

The 1133's are svo block only. I have them on my r-block. They do make mls gaskets for the stock block. I dont remember the part number.

 

i hate to tell you but they are fine i have them on my 90 gt stock block with stock bore roush headed 302 they marked the packages wrong mine are working great call summit if your worried they will tell you hope this helps you out matt

 

oh by the way i made summit price match autozone or advance auto parts sell them a little cheaper i think i saved 10 or 15 bucks

 

the bore area is moved out because when a head that has a larger valve installed, the valve would hit the gasket.

the only difference is the water pass slots near the boltholes.

 

i ran 1133 on stock block with tw's

 

about to use 1133s on my engine .. pics!

everybody sure these are gonna work ? , i did say svo only but the guy who put the valve springs on my heads said these would work and are the best ............. do i need to modify these at all ? or good to go ?

 

 

why cant i put a pic in the message ...

1133's

we got 1133's on un-touched stock block with TW heads and arp studs tourqed @110. leaked coolant a bit around the bottom bolts then quit after a few days. 10psi boost with a 80 shot of juice all day long with no problems so far. 1011-1's just didnt hold

 

The other difference I notice is along the top (intake port side) of the head the gasket is a flat line, where as regular non-svo gaskets have a hump around each cynlinder.

I found this website: http://21cgt.com/FMWebCatalog/default.htm that lists all their gaskets, and the 1133 is the only 302 MLS gasket I see with a 4.1 bore

 

well ill see how it lines up this week

 

FWIW, I used the 1133 gaskets on my 418W. I've put over 8000 miles on it with no issues so far. Car put down 589rwhp on a 200-shot while blowing through a Center Force clutch (haven't got any numbers with the SPEC yet).

 

and if you look at the bottom where each cylinder is closest to the edge...the 1133's have extra material where the 1011's dont.....thats where mine blew the gasket more than once.......well it didnt blow....it squeezed it out while eating away the graphite at the same time till kaput!!!!
