Head Gasket P/N for 088 on Gen VI
 

I am in search of the part number for the head Gasket when using 088 Heads on a Gen VI 7.4 Vortec block. I see alot of talk about the 088 coolant passages and Gen IV block but nothing on my setup. Any help is appreciated. I am comparing some cost on which direction to go with my build. Thanks in advance.

Depending on the bore it could be a Felpro 1037 for 4.25 bore blocks (4.37 gasket bore), or the 1047 for the 502 block with the 4.47 bore (4.54 gasket bore). Both are performance/marine suitable.

17048

If using the Felpro I also recommend spraying the gaskets with High Tack sealant prior to assembly. I've found that it helps seal the lower water coolant passages a little bit better than the silicone beads they have on there.

second that

If you order the 1047 you'll get a 17048. Same gasket.

I just pulled the heads and there is a 17042 on there, is that not the correct gasket?

Yes, for the 454 it is. Same gasket as the 1037.

I am going to assume that I will need ARP kit 135-3601?

can you post a picture of the top of the piston?
