The 1009 and 1039 are true racing intended gaskets -- they have a tin-plate internal solid core... but with stainless steel folded cylinder armors WITH an internal pre-flattened wire ring (racing intended!)... that creates a solid fire wall against detonation/pre-ignition hi-compression common problems.

The bore diameters can be a problem, pending how large you go.

Also, "casting holes" are always restricted by the head gaskets -- to control the flow pattern/direction and volume of coolant.

I'm a former Fel-Pro applications engineer... your questions are common.


Thanks for weighing in. I appreciate your input . Sounds like I would be ok if I chose either of those two
