Intake end seal gap
After replacing my headgasket I can't seem to get a good block to intake end seal.
The Weiand Stealth that I have has the ends milled down to almost flush. I can get a awesome seal intake to head, but have a gap of .160" between intake to block.
I am using Fel Pro 1250 intake gasket set.
Is this something I can make up with stuffing a heaping bead of "Right Stuff" and call it a day?
Toss the intake in the trash?
Have someone build up the ends with TIG welding and mill flat?
Use the cork gaskets with a good coating of RTV to make up the diff due to the milling?
Thanks for any help.

You might need to mill down the intake, did they take alot off the deck ?
-
Nothing off the deck but a slight mill to clean off the shit gasket. Heads were not milled again just enough to clean the surface.

bead of rtv and call it a day.
Danson and Highsmith, free hot dogs for life!!!!!
no drinks.....no drinks....can't do it....can't do it!

all i use is rtv black on both ends of the intake along the block. lay down a fat bead and let it set up for a couple minutes then another quick smaller bead on top of that and bolt down your intake.
-
Roger that a heavy dose (3/8 bead) of RTV it is then.
Do they make a thinner performance intake gasket set. Still want to block off the heat cross over in the intake.

3/8 of black rtv. never used gaskets for the ends. no leak

Right stuff is the shit! LT1s have that problem and dont even have gaskets for the front and rear of the intake. I use right stuff every time I pull the intake and never have leaks.

Hoping to be fast someday

I buy the stuff in bulk. So when I mean RTV its like slang for "Right Stuff". I don't think I even have any ultra black or gray.

try drilling very light holes in the intake or block and install very shallow dowel pins..use a thick bead of rtv and done! worked great when i had a fucked up head & intake combo once.
