    Purchased LS 243 heads from Custard Core Supply—Fabian was awesome to work with! He sent pictures of the heads for me to inspect the heads I purchased and then arranged fast drop-shipping straight to LME in Houston, and they arrived in just one business day. LME said the heads were in incredible condition and very well packaged. For take-off cores, the quality, condition, appearance, and value were excellent. Couldn’t have asked for a smoother transaction. Highly recommend, thanks Fabian!

    The item arrived 2 days after placing the order, which was excellent. I appreciate the prompt shipping. The part was well packaged and in excellent condition, new appearance, including gasket and bolts. When installed it functioned perfectly. The part was a great price compared to some other sellers. If I have the opportunity I will use this seller again with no hesitation.
