After nearly a year of development we're finally to the point where I can show you guys our newest LS based PRC castings! This all new casting is the PRC LS3 cylinder head & will be available in MANY different configurations ranging from LS1 friendly LS3 heads all the way up to large cube LS3 stroker applications! We don't have flow data or anything like this at this time, this is simply a post to let you guys checkout the progress & know we're working hard to make these cylinder heads a reality. The new changes to our castings will allow many new features on both the LS3 head & the cathedral LS heads! Keep your eyes open & we'll keep you guys updated on progress!
