I am finally going to be able to put some much needed work into my car. So far it has intake, longtubes, !cats, exhaust, cc503, and 1.6rr. Now I'm curious about what heads go well with this cam. Should I find a cheap set of stock heads and have them reworked to match the cam, or is there a better option? The car is mostly a fun car to drive on the weekends - and once everything is straightened out with the suspension and rear it will see the track quite a bit as well.

If you want headroom to grow into a bigger cam, as well as getting the most out of the CC503 for right now, Advanced Induction's 200cc ported stockers would get my vote. If budget concerns don't let you step to that level right now, or if you can't find a used set with a reputable porting job, then frankly I'd just run the stock heads with a good valvetrain until you can make a serious step up.
If you get the rest of the car right, high 11's with the CC503 and stock heads are do-able.

Thanks for the input. I didn't know that the 503 would get me that kind of times without head work. I will definitely be checking out the AI heads to see if I can swing them anytime soon.

Now time for a dumb question. I love the way that the red lt4 intakes look - so I've been wanting a red intake for a little while, and if I do that I may as well find a ported one - is there any point in getting intake work done at all with my current setup?

Nope, no point in porting the intake until you're making beyond 425 rwhp.
Just get some red paint and have at it
And just in case you're thinking of an actual LT4 intake, stay away from those; the LT1 intake is the better choice for almost any of the good ported GM heads out there.

That sounds a whole lot cheaper/better to me

And I had read that about the lt4 intakes (and heads for that matter) I was using it as a reference for the color.

yup what he said ^................stock LT intake is good for 400rwhp all day long.........and well more than that ported.......LT4 intake is the biggest waste of money on the planet.......also with that cam you'd be ok with stock heads........id say run it with good valve springs on your stock heads.......then when you ahve the money have AI port them to 200cc and run the same springs on the new valves........do it once do it right.......costs less and you go faster

good luck!!!

Thanks for the info everyone, glad to know that the heads/intake will work well with my setup...for now

stock or stock ported is the way to go , i ran like that in a 355 for 2 yrs and then when my new motor was just about done for the hell of it i bolted on a set of a.f.r 210 heads . lost a little down low had a great midrange and lost a bunch up top as the cam couldnt flow the heads . on nitrous though it ran great and got me my best time to date with the car . the cam got me a 10.82 , its a great off the shelf cam . yeah its dated but it still works and does well

t-rey

The car went 10.82 with the cam/stall/spray, or was that with the new motor?

Old 355 with the 503 cam . New motor is a solid roller 383 .

Wow, that's impressive. Makes me even more excited about getting my car up to par.

Ok I'm gonna be that jack *** who comes in with some of the same questions to be sure I'm reading this correctly being as I'm lookin at doin the same. I just got some coated LT ps. No real major mods other than bolt ons. Thinkin my head gaskets take the duce along with an oil leak that's gettin worse. So rebuild time. Since it'll be apart why not came it up also while doin headers. I'm lookin at this same cam. Granted I can't budget in good heads yet. So all in all your sayin that no real head work will be needed to be happy? I have new standard springs, keepers, n what not. So I guess what I'm asking what is needed over what can wait. Luckily my company has a dyno shop with good discounts. I hope I didn't loose anyone. Thoughts faster than typing.

no head work needed man , that cam works great with stock heads

You will need better springs though.

Better meaning new or lift capable? Also I've seen a lot on this cam....who makes it? Lol I know which it is and what not. Just never caught the brand.

CC=Comp Cams, the manufacturer of that cam and many shelf cams you will see discussed (CC305, CC503, CC306, etc). Google "cam quest" and you can see some of their grinds.

Valve springs - Better meaning lift capable (.540ish if your running 1.6, most aftermarket spings are capable of .540) and you need more seat pressure and open pressure for any cam above stock duration and lift.

Thanks you. This is the exact answer I was looking for.
