RHS has released a new 260cc LS3 cylinder head with 3 options for springs or bare. No information on these, no flow numbers and the RHS web site has no info on them as of today. Real poor launch on RHS’ part. Called their tech line and the tech new nothing of them but then called back to tell me they came out a week ago and there’s “nothing to tell” about them. Prices are $449 bare? to $699 for best spring option.

 

I know of two things.

1. Aftermarket LS3 heads are not really any better than OEM LS3 heads
2. Rhs from memory, would be less stout than the competition however I may be wrong on this.

 

This is an inexpensive alternative to redoing a set of LS3 heads. Be interested in seeing flow numbers, not a 12* head

RHS wonders why they’ll never have a real presence in the ls head market. Common sense says clue in your sales staff with data and dyno results Prior to releasing new product. What a joke
