  • DISCLAIMER: There is a known issue with factory GM LT cylinder head castings causing the factory valve seats to fall out. A valve seat failure will result in a damaged head and possibly a catastrophic, irreparable engine failure. It is common enough to warrant discretion when using factory GM LT cylinder head castings. Texas Speed and Performance assumes no liability in regards to this issue since it is a factory defect. Due to this, we highly recommend purchasing a set of our aftermarket LTx cylinder heads. This disclaimer applies to all GM LT cylinder heads, regardless if you purchase them from TSP or if you supply them for us to port. Precision Race Components is proud to introduce our CNC porting service for your 5.3L & 6.2L LT1 cylinder heads! We do offer CNC cylinder head porting for those customers wanting to send their cylinder head castings to us for complete porting, competition 5-angle valve job, and professional assembly. This service does NOT include the cylinder head castings, only the porting, competition valve job, professional assembly, vacuum testing, and milling to the customer's specs. The PRC ported gen 5 L83 & LT1 cylinder heads are an excellent upgrade for customers looking for more power than what the factory castings offer. Pair our PRC ported gen 5 cylinder heads up with a TSP LT1 or L83 camshaft that was designed on our SuperFlow engine dyno for maximum power! Ask your sales professional how you can gain 100+ HP today! CNC Porting Your GM Castings CNC Valve Job CNC Custom Milling To Your Specs PRC Spring Kits available! *Typically a 1-2 week turn around time once heads arrive at our facility.
