I have a set of Trick Flow 6 bolt LSX cathedral port heads for sale. They include stainless steel 2.1/1.6 inch valves. I also have a set of 1/2 inch thick 304 flanges that the heads were matched to for 1 7/8 primarys if you are interested. $2000 obo 727 215 8620
These are hand ported. I never got around to buying springs or retainers for them. I will have port/chamber cc info and a flow sheet within a week. Just a guess but I have worked with the man who did the porting before and I'm expecting around 350 cfm at 600 lift. The heads are new/ never used. The chambers were carved out to accommodate a 4.03 bore. These are not 245s. They are a porter's casting. More info on them here.
ok one last question, do you know what they cut the valve seats too, like 45-55 degree angles, also as you already mentioned I need the cc of the chambers and if possible the intake runners , and are they set up for solid roller or hydraulic and the valve length or I guess I should probably just call you if you would prefer thanks..don
They have a 3 angle valve job. 55, 45, then 35 from the outside to the inside. I'm not sure what angles are on the valves. The valves are .100 longer than a stock ls1 valve because of the raised spring pockets so the valves are setup for a 1.8 inch installed spring height. When I cc the chambers I will cc the intake and exhaust ports at the same time.
I can have my head porter open up the chambers for you boost guys if it gets the heads sold. Flow numbers coming on Wednesday. To the people that I was texting back and forth with, my phone died and will be working again in the next day or two.
The flow numbers are in. Sorry for the delay but but the shop that I took the heads to kept putting me off. Intake .100/88 .200/141 .300/200 .400/258 .500/293 .600/305 .700/305 Exhaust .100/96 .200/142 .300/193 .400/238 .500/264 .600/273 .700/285 The testing was performed without a form or clay on the intake and without a pipe on the exhaust. That being said I think the exhaust ports performed very well. However the intake was somewhat disappointing. My head porter reminded me that I specified that the intake port must match up to a stock ls6 manifold which is the restriction. Unless someone is interested in using these heads with a stock ls6 manifold we will open up the ports and retest.
