i guess it would also depend on the year. some k20a2 heads were dual valve spring, some single.
oh, and the k20a has a red valve cover
which head is better? what else is going on w/ the block? all motor or boost?

i'm thinkin of nitrous, or boost...but, i havent even got anything, i know the block i want, jsut trying to pin down the head choices.um, not all motor, but, just kick *** motor.sleeper is the game.i have a weird philosophy, i figure, why buy another car, jsut custom the ride i'm in, keep it for life, then i'll tuly be satisfied with it.hell, bury me in it.

Rep Power: 0 um, me newb..will that effect performance? which one would be better for torque? i mean, i'm sure it would be a minimal diff..but..if its enuff, i may consider it.the type-r i mean.

Both heads on a K24 will get you the nearly the exact same power. Why?
Well all the extras done to the K20A head give it more power in the very high RPM range. The K24 is not really a high revving engine. In short the K20A head makes power in an RPM range the K24 block cannot goto without some major modification. Its kinda like getting an intake manifold that makes max power at 12,000 rpm and slapping it on the stock D17.

Rep Power: 280 Compresion Ratios..
Type R 11:1:5
Type S 10:1:2
(or around there not exzact)
Which K20 is it going on a Tsx or a CRV?
NA Ide go for the Type R personaly on a TSX... more power in theHigher rev than that type s (as long as the K24 can hold it) ie 7800 vs 8400. If your boosting then go Type S on CRV. (once again compresion key to everything)

Rep Power: 280 okay sue me got the numbers confused,.. you sure about the type s, i dont think its 11, im pretty sure its 10 something. ive looked it up before i just cant find it.

Rep Power: 0 But ist the TSX engine able to rev a little more, out of the box the TSX rsv up to 7100 vs 6800 of the CRV, with the K-Pro it goes up to 7300, so the bottom end internals between the TSX and CR-V would be different right??

I forget at the moment, but there is a ratio that has the final say in how high you can safely rev. I think its the rod length to stroke ratio but I could be wrong. Anyways the point is, is that this is how the K24 was built, not much you can do about it aside from getting a custom crankshaft made. And having a machinest do some work on the bottom end.
In short the K24 was made to make torque so it can pull around the heavy TSX, Accord, and the SUV it goes in. It was not made to rev out to 8000 rpms like the K20A/2 was. There are a FEW people with a K20A head on a K24 block revving out to 8000 rpm (most are making about 230 whp) but you can bet they won't be doing this for long.

Because the quench area of the heads are the same, because as another member said they have the same castings, so putting a K20A head on say a K20A2 WILL NOT increase your compression ratio. The difference in compression ratios is because teh DC5R has different pistons. So putting a K20A head on K series blocks wont bump up your compression. That is unless the K24 out of the TSX came with a larger quench area, and by putting the K20A head on your are reducing the quench area, thus increasing compression but this is doubtful, because the engines are so similar I doubt Honda would give them different quench areas.

Rep Power: 403 a tsx or crv is not safe above 7500... its not going to last too long. a k20a2 or a head on a 2.4 block is going to yeild more hp than a tsx or a crv anyday, because of the cams and the larger head ports. because the tsx and crv block can produce gobs of tq at a low rpm, you don't need high revs to make gobs of power, look at v8's they all redline at like 4000

Rep Power: 280 If you wanna rev high, just get a k20A if you want torqu get a k24 simple as that.
*but eairly i was refering to the compretion ratios in the k24 with a k20A or K20A2 head being different, Thats because there is more than one type of k24, they have different ratios, and clerences if you add those particular heads. It will change the ratio.*
