That's the bore size the gasket is for. I don't remember exactly, but the gasket was about 4.155 I think.

Picked those gaskets up today. Should be here by Friday. Boy does this piss me off. Guess I need intake gaskets too.

Shafiroff builds this engine all the time. They sell it as a package. Which means those dipshits use the wrong gaskets day in and day out

Maybe it seals just fine till warranty is out, or they address the issue on assembly.
Either way, they ain't telling you for free.
 
did you contact Schafiroff?
 
Tomorrow morning. Can't wait to hear the bullshit
 
Actually, I just recalled the post about the owner saying something like they don't know the bearing clearances and the lifter bores might have to be run through with sandpaper or something... :rolleyes:

(I think sandpaper is an exaggeration but it was pretty bad)

Look on the bright side. You caught this before the dyno session. I know it’s frustrating, but every mother fucker on this site has been there. Give yourself some credit, you have caught a lot of potential problems and fixed them.

Sucks to have to clean off the silicone though. Make sure nothing falls inside when scraping it off. It shouldn’t be too bad working carefully with a razor blade. I usually drape lint free rags over the valley, so nothing falls inside an oil passage.

What head gasket are you using?

He text me yesterday and asked the same question, but I am using the wrong ones. They work, but they are wrong. Eventually I will change them.

Felpro 1011-1 and -2. They are somewhat oval shaped. When I had one of the heads off last year and took it to a ford engine builder’s shop/house, he said they were for Yates style heads. Description on Summit says nothing about it and the pics look like perfect circles, so they are likely just a representation.

Oddly enough the 1011-1 is what was on my original build, as well as the 2nd time it was built. Although I don't quite understand what your issue is with them because my brain wasn't/ isn't working
 
Wait, how the fuck do those work with your 4.125 bore?
 
Just for an example of typical fuckery I've been shaving new cam bearings the last couple nights. Same old block, same old cam, new bearings of the same brand but a snug spot on the rear bearing.

Isn't it the hole in the block that's different than oem?

I don't have any pictures of the oem 351w vs the dart one. My old block is all oiled up and wrapped and I don't really want to tear it open
 
Yes, I’m fucked on the head. I guess I had that number gasket for so long, I defaulted to it.

I’m using the M-6051-B341’s look at the shape of the rings. They are all goofy.
