Heads for a TR224?
Heads for a TR224? I've done several searches pertaining to this subject, but haven't gotten a clear answer. What heads are a good match for a TR224 with a .563 lift or a smaller cam? The reason I don't want to get a bigger cam is because I like running the 918 springs due to less pressure on the lifters and not needing to swap springs so often. I always read about awesome heads and great dyno results from them, but it's always with a much larger cam than my TR224. Which heads would net some nice gains with this cam? I've been reading up on the LS6 heads that TSP has for $850 or so, which are very tempting, but don't know how well they'd do with a smaller cam. It's about time I took the plunge for a set of heads and any help would be appreciated.

Why's that? I mean, if money wasn't a concern I would also opt for the 205's, but that's almost triple the cost of PRC ls6 heads. Would the difference in hp be that substaintial between the two heads to justify the price difference (considering the size of cam)?
Krab, It's all about what you want in your setup. If you are going to be happy with 410-420rwhp then a budget head should work fine and suit your goals.
^^ agreed. I don't think that the extra money is worth it, (IMO) but for someone willing to spend the extra change, its obvious the AFRs are better than the budget heads. (trying not to contradict myself there). I'll save the money and get the PRC heads ls6 casting w/ 918 springs for around 1k.
I am running Absolute Speed heads, but since they are not in business anymore I'd suggest anyone who can get the most out of the head in low lift situations. The cam doesn't exceed .563 (mine is a .561) so you don't need a head that flows in a lift range that the cam will never see.

I am goin to be running Dart 225 with my 224/224 .576/.576 112lsa crane cam setup. The two reasons i went with these is first off i got them dirt cheap (cant say how though). The second reason is that most of your budget head are gunna be around the 230cc + intake runner size. That is where they get those great flow numbers. But the head wont make as much power down low are as say a 205cc head will. The bigger the intake runner the higher the rpm needs to be for the head to generate air velocity (That is my understanding). The darts are a 225cc head but the only downside is they have a 2.05/1.60 valve which is a lil big but we will see what happens. Ill get some numbers up when they go on.

TEA 5.3 heads are a proven winner with the TR224. For a street car I would be looking at their stage 1 or 1.5 heads.
The PRC stage 1.5 heads would be good as well. I happen to have a set of the PRC stage 1.5's waiting to work with my TR220 camshaft.
You should be looking for heads with as small of crossectional area as you can with good midlift flow numbers (0.200 - 0.500).
Good luck.

I was around 380 with cam only, the addition of the heads put me at 409. Now I have gutted the "very restrictive" TTS cats and installed a Exedy clutch, so I am expecting to be at or slightlt over the 420 mark at least.
Then again, Jay no longer exists. Today I would go AFR 205 just incase I went bigger on the cam.

What about doing your stock heads-with your mild cam it should be easy to get some good flow #'s. But like most of us on here, our first cam was nice. Once you have the itch you'll want to go bigger so it will be nice to already have heads that will be up to the task of handling more air.
