Fel-Pro Loc Wire gaskets are engineered to provide the best sealing available for severe applications. They have oversized wire rings that lock into receiver grooves which must be machined into the cylinder heads. Precise machining is critical to the success of these gaskets.

Mike was rite,,the 17042 is what you want to use on your engine..i would also buy a set of head studs ..studs make a true torque spec so every stud/nut has the same load..a head bolt will vary in uneven load to the cylinder head..

like I said I don't think it is a Loc Ring, I believe it is a pre flattened steel wire. no need for a receiver groove?

1)The strength of steel wire sealing with minimum brinelling of aluminum heads.
2)this is how i read it,
which tells me machined groves need to be in place..i went through this with another guy that used this gasket and they leaked water into his cylinder and hydrolocked his engine..
3) 17046 is for a mark motor not a genV
I dont believe he has alumium cylinder heads,the 525 sc were cast iron..

the 17046 is for a mark4 block.it comes 3 different ways.1-a pre flattened copper wire.2-a pre flattened steel wire.3- a locking wire ring that requires a reciever groove.i personally would never go with option 3,if i was build an engine with high cylinder pressure i would go with a mls gasket.if a nitrous or blown alcohol engine i would entertain a copper gasket with a o ring and a reciever groove.

Got the two gaskets I thought might work.Turns out the 1037 and the17046 are the same gasket the 17046 is just labeled marine on the package
Came with these instructions.
Has anyone done this and had no cooling isues
these gaskets also have only one hole in the side the other is blocked off.
By the way it is a gen 4 block I replace the gen 5 that it had.
thanks Guy
