Head gaskets Pro1 406SBC

[lastchevelle]

What FelPro head gaskets should I use with Part number 11511123P heads? Engine bore is 4.155, no steam holes in heads. There are about 4 different gaskets that I think would work. Just want to buy the right ones the first time. Thanks.

Use FPP-1143 Multi-layer steel

If that's a Chevy 400 block, you will save yourself some headaches by drilling the steam holes in the head.

Do not forget to chamfer the steam holes in the block and the steam holes you drill. Everyone does not do this and sure as the sun rise, the block and heads will crack. That is what causes both to crack if not chamfered. jtusno
