Ryan is spot on. If you are going to swap out the heads, you'll need to pull the intake anyway. And at that point, get the intake reworked by Raylar so it's not the weak point anymore.

If you drop the coin on the heads you are only $700 away from having the cam and the rockers. Dunno about you but tearing it all down and NOT doing that seems crazy. At that point you are at 525 HP. With the 525HP Raylar cam its basically a hotter HO cam. The intake on the 525 setup doesnt make a huge flow difference. On the 600, more so but a jillion years ago Ray told me it was like a 25 HP difference and I think (I cant remember) but if you just gut the throttle body intake to 90MM you are pretty close to the fully ported stock intake. BUT, I do know its a bicht getting all the grindings out - because I did it.
I did the CNC heads from Crockett in Michigan, raylar 525 cam, raylar rockers and I ported the intake. I have no idea on HP but it was faster.
FWIW, I wanted to do the HP3 cam but the piston to valve clearance was like .030 and i couldnt force myself to do it. I know its possible but with the springs I had I just didnt think it was possible.

At this point the only one actually producing an intake manifold (from scratch) is Whipple as far as I know.

There's no $$ in it for a company to beat a dead horse. Raylar has the Coolgap. Dart makes an aluminum intake with 4150 flange. This covers the carb guys and retrofits to a Holley EFI conversion. Most will run the ported stock intake which can support pretty good hp numbers if a 90-100mm tb adapter is welded onto the intake. I believe Raylar made 580hp with ported stock intake with the 600HO kit.

Take my setup...... It gained some power and runs great. However, I bought the cam, rockers, coolgap for cheap $$. Installed myself. If I would have bought new and paid for install, I would be HIGHLY DISAPPOINTED!!

I don't believe many have gone just the "heads" route. The stock intake then becomes the restriction. Baby stock cam does not take advantage of the new heads. The smaller cc of the Raylar heads will put you around 10-1 scr.
Old post by Raylar when they were dyno testing their new heads in 04' stated......... 496HO with just our heads and a slight fuel pressure increase made 478HP @4800rpm and 536ft/lbs torque at 3500rpm

I will try and make this short and simple. 496HO with just our heads and a slight fuel pressure increase made 478HP @4800rpm and 536ft/lbs torque at 3500rpm. We added the roller rockers upped the fuel pressure a little more and made 504HP@4800rpms and 541 ft/lbs torque @3600rpm. We added our new intake manifold and and a 85mm throttle body and made 531HP@4850 and 576 ft/lbs. of torque @3600rpm. We have changed the cam in the motor to a better profile and we think we will see 550HP on Monday 6-7. We have been down on the dyno for over a week because it broke the strain guage and we had to wait for a new one from Superflow. We have already made over 65 hard dyno pulls, some up to 5500rpm and we have had no problems, wear or breakage in any parts on the motors.
Our production heads are cast and in machining as I write this and the first manifolds should be ready in about two weeks.
Thanks,

Since each of us is entitled to our opinion, I honestly and absolutely don't think he was a hot head when it comes to speaking about the development of Raylar's products. He was honest and passionate about the product. It's the reason I am here. Many have had success and I am enquiring. Sorry if you may see it differently.
