EPS 234/246 & head choices So after quite a while of slacking on my car due to them getting stolen often in my area I've finally gotten tired of looking at my car just sit in the garage. I've done some searching on here but it seems only a handful have posted about this cam.
I'm getting ready to finally reassemble my engine as it is currently in Shortblock form.
I have some 241 heads laying around I may just throw them on there to get my car running but first I wanted to see if anyone has ran this cam and what heads did you end up going with.
I was going to have Tooley do some TFS 220s but I plan on building something over the next year and I'd just like to get my car running asap while keeping a tight budget.
I can also get my hands on some stock 243s or should I port my 241s or even step up to some TSP 5.3s? I'm not going to flycut as I don't have the ability to and all the machine shops out here want to remove the Pistons to do so.
I'm not looking to spend much more than $1400 on heads since I still need to buy an Intake, TB and a built trans.
Thanks for the insight.
Also my car is sub 3220lbs , if that matters.

FWIW car will have 4.10s, 4200+ Circle D 2E stall and possibly more weight reduction and will be on a 17x4, 15x10 racestars setup. Is no longer a DD either obviously. I will mostly 1/4 this car with weekend street duty.
Just send the 241s to AI for the HCR option. That way you don't lose any PtV clearance and can still have 60cc chambers or so (would probably be ideal with that cam). Also, the intake and exhaust ratio would maintain similar to stock ratios, so the cam timing would work well. And at 1145+shipping, it fits your budget.
Hell, I have a set of 241s sitting here. I was thinking of picking up this 2004 Chevy 1500 around the corner from my house. It has a 4.8L motor and is jacked up 10" with 38" tires. It would need more motor. I've thought about grabbing a junkyard LQ4 and running HCR 241s with it with a 220s cam and a 3000 stall. That'd be a nice daily driver... haha

The plan next year is either a 400+ ci stroker NA build or a turbo build. I'm undecided currently which is why in just looking to get this car running but also make somewhat decent hp within a budget.
Basically get the car running and drive it while starting my build on the side.

Verdad Gallardo If you do the 400cid, do the MMS 220s or 235s or Frankenstein or Mamo worked TFS LS3s.
I've been toying with the idea of running a 402 under my TEA heads since they are 226cc and have a 2.04" intake valve. Very good efficiency with that head on a 4" bore. But if I were to step up to a 4.070" LS3-based stroker, I'd probably do the MMS 235s. They are more efficient if you use Tooley's formula for intake valve size to flow to lift. And that's with a 2.10" intake valve which would be awesome on the bigger bore.
The issue is, I think I could hit 520rwhp on the LS2 with my current heads. And I'd be around 550 with the 235s on a 416. Not really worth an extra $3500 minus whatever I sell my TEA heads for. And swapping over to the LS3 doesn't make sense, because I already have the FAST. And I hate trying to sell ****. I'm still sitting on a ton of stuff.

Big stall A4s don't dyno. But they run like crazy. So if that 585 is through an M6, that'd still run hard in front of the 2E.
I could see a 129+ trap speeds with the 402 and my current setup truthfully. That's a pretty quick street car with no power adders.

EPS 234/246 & head choices I know Geoff is a big TEA fan from the results he's gotten in the past. I'd personally just call him and see what he'd recommend for a head with that cam. He always answers when I call.
If you just want to get running with the EPS cam, why not just use the 241 heads stock. The money you save could go towards a intake & TB you will use on the "real" build.
Also, could someone ask Geoff what the ground in advance is on the Truck Torque 3 ? I asked him this in a PM but he never replied.

TEA has a port program for the 241s. But given the HCR option from AI, I'd probably lean that way. If you had 243s, I'd probably lean back to TEA. And if flycutting were in the cards, the Stage 2 program from TEA would be the way to go to maximize the 346.
One thing I've looked at is the AI 232 program with the 2.055" valve for a 4" bore application. I think that would make big power at a much more reasonable price than the aftermarket head options. I've even toyed with the idea of sending my TEA heads to Phil to let him open them up to 232 and install bigger intake valves in there (which TEA can also do - thought about that option as well, the Stage 3). The exhaust probably could be left untouched.

I think it might be worth it to get the Tooley worked TFS 220s now and put them on a 402 next year. I don't know the cam there or if this was the 220s with the 2.04 or 2.055" intake valve, but 500/490 is pretty good. The TFS 220s could definitely support a little more power than that. I think you could see close to 520-530 if they were worked over with a more aggressive camshaft. To me, that would be a good use of funds now and in the future.
Sort of like me thinking the TEA heads I have now would work fine on a 402 for close to 500/500.
