Texas Speed PRC Mail In CNC Ported Cylinder Head Service – LT1 & LT4 Engines – #199-LT1GMPORTING

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!
