Default FIRST PICS PRC LS-3 Aftermarket Casting Cylinder Heads Sneak Peak INSIDE!!
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!

im guessing that these are going to be compatiable with non 6 bolt blocks like other 6 bolt heads?

can you ellaborate a little bit on that? do these castings have all new features that are going to be used in the cathedral port heads or are you making some monster interchangeable head?

Very cool, finally an LS3 deal without giant intake ports! Looks like it will have some nice features too.

Looks interesting! Will it be made for an L-76 intake? That would be a huge plus over having to buy a FAST intake from a cost stand point.

Its setup to use the LS3 or the fast intake no problem. We moved a lot of these updates over to the cathedral head including the ability to run LS3 rockers.

hmm. tho the small runners look like theyd be better suited for an ls1 style fast, except for the whole raised runner aspect.

PRC is a stand alone company. TSP retails the products.

When you say "LS1 friendly" do you mean these heads will work with LS1, LS6, and LS1 style FAST intakes?
