Help required - Best value place to get a D2 head gasket from?

[James Eastwood]

I've been interested to read these other posts, almost forgetting I cam here to ask a question!

I look after a 100D2 which has a slightly further raised compression ratio. My head gasket is beginning to leak combustion gas into my coolant and it doesn't run at full throttle. I don't have the gasket off yet, but believe it's standard thickness.

I know INRacing will sell me a gasket. They're obviously very good, but at a price. What are the other sources of Bristol gaskets in 2025 that I might consider please?

Thanks James
