Thinking of selling my 360-1's I have now and getting the big cnc ported ones. The motor is a 14 to 1 R3 59* motor with a solid roller 281/288 @ .050 with a .661/.664 lift with a big shot plate and a fogger. Feedback please Last edited by a408swinger; 09/25/08 09:27 AM.

We have had great luck with the 360-1 CNC-245 with flow over 330 cfm @700 with a lot of compression.Other than touching up the valve job and correcting all the spring height They are pretty good the way the come.

The car is 2940 with me in it and its been a 5.60 @ 127 on the sauce so far but havn't had it on the dyno to tune it yet. A good friend of mine is looking for some 360-1's so I thought about selling him mine and stepping up to the 245cc cnc heads. Mine have already been ported and just curious if I will see an improvement with the cnc heads over fully hand ported heads.

IIRC, flow was a little unstable at most of the usable lift points. 4709112-DSCN1596.JPG (203 downloads)

I would'nt use the RP on a 408, unless it was a methanol engine. Both are designed to be ran with 2.14 or 2.15 valves. The RP port can only be put into newer raised valve cover rail castings. I posted Dyno #'s off a 245 non RP head motor that was hampered by a 2.1 valve (was forced into running this) about a month ago. Those were out of box untouched heads except a VJ. There is more flow to be found with a little hand work, but you can make substantial power with their OOB ports. I've now gotten to see several sets of ICH CNC heads off of running engines & the chamber burn pattern is exceptional on them. Many complain about how BIG the CNC chamber is, but I'll take killer burn every time over a head with smaller less efficient chamber.

Port entrance is 1.375" W X 2.40" Tall.... that's a big b.... 369W7's set have been modified port wise, so I think I'll throw a valve in these new virgin RP's & CC a runner to see what they really are out of box. I know it's bigger than 245.

The std port height "245" head must be smaller than 245. I've only had 2 sets of those here & never measured them volume wise. 369's Modified set are 254 CC.

The motor is a 408 now but I may go larger down the road. Im looking for max power. I run this car in a stock suspension 28 x10.5 tire class and run 2 kits (400 hp total) Can they be ordered with the bigger valves? Im running a 4.035 bore now, just wondering if bigger valves will fit. The pistons are custom Ross domes. Im ordering just the assembled heads, I already have T&D rockers on the heads I have now and my friend thats buying my heads already has the Indy rockers to go on them. Im looking for max power. My motor makes peak power now at 7600 rpm's. Made 530 rwhp through a Dana 60 and ran 6.30's @ 107 through a glide in a 3200 lb car with driver. My mustang that the motor is in now runs 6.40's @ 109 in the heat of Summer with only a 3.73 gear and a tight converter. Its 2940 with driver. 369's Modified set are 254 CC.

The N20 will also eat up runner volume just like methanol does. They come from ICH with 2.14" valves. They will be fine as far as hitting anything with the 4.035 bore. (won't be close) Whether they will clear your custom Ross pistons, I have no idea, but if they were designed for the ICH head with the 2.10 valve I would think they put enough radial clearance in them to be ok with the 2.14. Call them with your custom order # & I'm sure they can tell you for sure. You have alot of cam, & are spraying, the RP head should be fine. Just be aware there is very very little material at the top of the port for the intake to seal on.. if you try to reuse your current ICH intake & you'll have to make custom intake gaskets. We buy Raw ICH manifolds & surface them ourself to leave maximum width on manifold so it sits as high as possible on the RP head.

INDY won't make one, I asked Russ at Carlisle & he said not enough demand. So gotta buy blank Fel Pro material & get out razor blade & make your own.

If you have a gasket cut like you want, I can get SCE to make it. They'll want an order of 20 or 30, but they will make it, and whatever thickness you like. I have them doing copper embossed W2 exhaust, regular exhaust in both round and square, and they already make very nice W2 intake gaskets in 3 different thicknesses that fit Indy's cnc -2 head with room to spare!

What about trying to get in there some other type of intake? mybee some w8 or w9 MP intake or perhaps going to a chevy intake, i know i few guys are using the w8 intake on GM motors!! ryan?
