What are the best heads for the LS2 stroker and WHY? 2 Categories:1. Good streetable HP and TQ with a 220/224 cam? Intended use-blasting the road racing course and hauling *** in general. 2.Best value? And, to make this interesting, what about the LS7 head-will it fit?

Opinions please

The ls7 head will not fit because of the valve size. the ET ls7 head will, if you get the version made for a 4 inch bore.

With a cam as small as you are planning to run, you're most likly gonna be best off with a small chambered head, because with a cam of the durationb you plan to run the motor will run out of steam at a relativly early rpm, so a head with good velocity will probably work best. I'd suggest a set of the 215 or 225 et heads, or possibly the 215 trickflow, 205 afr's or the 205 edlebrocks.

The ETP 240/245 is a good choice for a large runner, standard valve location cylinder head. Big enough to feed the 400+ inches and able to use standard valvetrain pieces.

^^^werd on the et 245, plenty o power being made with those heads,

I'm using the 240 ET heads myself, but with the cam that he wants to run, a big runner head like that probably won't really do him any good, the velocity of a smaller runner head would probably be a better deal.

I just had a customer with a 402 that had made 470 with a PP head, then got some other heads that didn't make it to the dyno before they broke, and then ordered the new TFS 225 head and made 550 RHWP, I think there will be a post on them shortly. The business was Sunshine Performance.

AFR 225.

Oh yea, TFS is dyno testing their 225 against another 225 on a 402 as I type.

AFR 225's and LS2 strokers go together like baseball and hot dogs (with a beer of course).

Seriously, AFR 225's have been extremely consistant in their abilities to deliver solid results....especially on the more well thought out combinations which will always be the case. The average results are above average with some real good results in the mix as well.

Spending some time doing a search will certainly back up what might be dismissed as a "tainted" opinion.

Feel free to contact me if your considering moving in that direction....

Check out Cartek. You pay more but their results speak for themselves.

Yeah I bet that will be a good valid test.

Hey Tooley, instead of bashing all other head manufactures why don't you just let your heads speak for themselves?

I'm using L92 heads on my 402 with the L76 intake. I have no idea how they are going to work but on paper with the right cam they should make big HP. I should have it finished in about 3 weeks.

I do not believe anything those guys say. I have dealt with them in the past. They have no clue and Mike has lied to me in the past.

80rwhp difference with just heads??? HHHHHMMMMMMMMMMMMMMMMM

for what he is describing it doesnt seem like he would benefit from big runners like 240 or 245's. at the same time he might be choking the motor with 205 or 215's. with a small cam(especially for a big cube motor) seems like you would be best off with a 225 head. you may not make as much peak but seems like it should better mid range for your application.

ZO6er,
Since you said that you want to blast around a road racing course (not the quarter mile) and good streetable HP & Torque; I think that you might want to consider some smaller intake runner volume heads (like in the region of 200 to 215). The 220/224 cam might be fine, but again you might want to consider something a little smaller in duration (like 216/224 with about a 114 LSA). As I see it, you are mainly interested in torque production in the 3,000 to 6,000 RPM range with your stated goals.

what do the AFR 225's flow out of the box? from talking to some people they seem to think it is less than some PRC heads....i think someone told me ~305cfm @ .600 lift max and i was flabbergasted b/c i thought those afr's flowed upwards of 330cfm out of the box. :shrug:

In the original post, he mentioned he was building a stroker LS2 with a fairly small camshaft. To feed a big engine with a small camshaft you better have a good sized cylinder head on there.
