Fel Pro head gasket comparison

[Rory428]

I have been using Fel Pros 1020 head gaskets for years, but wondering if anybody has any specs for the regular 8554PT FE head gaskets. Seems that information is readily available for the 1020 (4.400" bore, .041" thickness, 10.1 cc volume), but I haven`t been able to find this info for the 8554PT.  I have seen 2 different thicknesses listed (.048" and .0572), quite a spread. I know the bore shape is irregular, but has anybody actually measured a 8554 for thickness and volume? And anybody use the 8554 for moderate performance use with aluminum heads? Just trying to weigh my options for when my new pistons finally show up. Thanks.

This is the info I've compiled, foe FE head gaskets. I find the 8554 PT is listed as .051, some on this forum call it .053. It a good gasket if your trying to bleed off compression. A better one, if your trying to max compression, with that thickness, for up to 4.16 bores, is the 8045 PT.
