EngineQuest’s 2023 LS Product Lineup


Hi, I’m Brock, the National Account & Marketing Manager here from EngineQuest at AAPEX 2022. I’m here to introduce our newest line of LS products. First we have our CH364X and XA cylinder head. This is our first performance-based head that we designed between an LS3 head with stock LS3 valve train and rocker ratio. This head was designed with an LS7 intake runner for better flow with the only requirement is that you use an LS7 intake and rocker bolt to run this head.

We also carry the 317, 243, 364, and 364X head castings, along with a full line of head bolts for all LS block applications.

Also in our lineup are system coolant plugs, oil galley plugs, roller lifter guides, oil filter adapters, valve cover bolt sets, and upgraded trunnion style rocker arm sets. These items are brand new to the EQ line of LS timing covers for early and late models, with or without the sensor. LS rear main seal housing, high performance LS stud kits, for early and late models, along with the upgraded white stripe valve springs.

And last but not least, the big block line for the 454/502 Chevys. We now offer both timing covers with or without the sensor. Come by and check us out at PRI, or visit our Website for our full lineup of parts and options at www.EngineQuest.com.
