Overall Assessment

Customers highly recommend our product for engine rebuilding, specifically noting its excellent fit and usability in various engine models. The price is appreciated and the gaskets are reported as both practical and high quality, with special mention to the Graphtite head gaskets being favoured for aluminum heads. Some users noted minor fitment issues but overall, the product's stellar performance and dependability for engine rebuilds is widely noted as superior to others. Perfect for antique flathead and 1950 8BA engine models, it is regarded as a tool with ample quantity and variety for any builder's needs.

I would buy this Gasket Set again. This is my 2nd kit.

This will be for a rebuild of my Flathead. I already had it completely assembled, then I finally located a Mercury Stroker Crank, so now she'll be coming apart again.

Packet well, all as said, fit is ok , you may need to trim some ports to fit your flathead if it's has been ported , but that is the way you do it. head gaskets are very good, and good fit.

Does this kit and the Fel-Pro kit (Part # 344FS7525B) come with the same gaskets? Is one more complete then the other? For example, the Fel-Pro kit only mentions the timing cover gasket, while this kit mentions, in addition, a one piece timing cover seal. Sorry for all the questions, but shipping to Brazil is expensive.
