Ls3 418 what heads to go with?? I'm going to upgrade my 68 camaro ls1 to a ls3 418 and I have a kenne bell that requires me to stick with cathedral heads..so what are the best cathedral heads for a 418??
LS7 small bores. Make sure to stay with TI intake valves, and make sure to use lash caps on the valve heads! You'll still be able to run your stock rockers w/ trunnion upgrade. This set will run you 3k. Just my .02.
Edit: just saw you said cathedral port. Boy, if I had the bore size, I use the rectangular ports in a second!

I sent you something earlier but I'll say this for the amount your going to pay with Custom sheet metal lower intake at a MIN. 3 thousand dollars you still have to buy........ heads......that's another 3 grand ....Keep it Simple, get good set of heads TFS 235-245 will probably be your best bet, they just seem to always perform great no matter what the build F/I.....N/A...etc... you'll have extra $$$$$(from not buying the lower intake) to buy all the good stuff to boot Valves,rockers-arms,..etc.

Do people even read the OP's posts before they answer? He said he needed cathedral port heads to fit the KB he has.
TFS 235's will want roller rockers so factor that in. AFR's can use stock rockers and will also perform very well. Mast is probably King of the Hill but you will pay for them.
Just my $.02

I thought TFS you could use stock rockers.
I put YT on my TFS, but that was back when everyone thought you had to.
I have stock rockers on my 245 Mast now, with the comp cam upgrade.

As far as cathedral port goes, you can't go wrong with AFR or TFS. I know the price difference between the AFR 245's and TFS 245's is minimal, but the price difference between AFR/TFS and MAST is pretty high.
