I have been testing the L92 and Ls7 and C5R heads for about 2 years on several setups from large to small for drag racing. I was wondering every ones thought on what cathedral style head was capable of making equal power as the LS7 or
L92's. I am in the process of putting together a 440ci LSX test engine and want to test some cathedral ports against my WCCH L92 numbers and my PRC LS7 numbers I made 680hp with a 440 11.1 and a set of Richards L92's I want to try and duplicate those peak numbers with a set of cathedrals and see what the torque does ? Whats everones thought on heads to try ported of course ? Thanks in advance

ET 255's, I have a set of 240's on my 402 and they have certainly lived up to and surpassed my expectations.

ET/LX is the best casting. Don't oved look setting up the dart castings, Ive seen them do really well. But them agian the old 243 can too.

edit, whats with these stupid *** banners?????

I am using the ETP 265cc heads. They intake ports are quite large.
I believe these are the largest cathedral port head available.

Is ET still making heads ? I have another 440 for myself with L92's I just took off and I ant to put the ET 265's on it ? I want a small chamber head for 13.1 compression. What rocker do the 265's use I believe they are ET specific right ? what about itakes, how bad is the port match with a super victor or equivalent ?

Yes, and no. Cary @ Performance Inductions took over ET. I may have the name of his company wrong, but you probaly know who I am talking about. He is trying to right the ship with ET and such. The exact details I do not have on what is going on over there, but, I do know Cary has turned out some nice stuff
