Not to start the war of these heads are better than the other ones we allways get into here. But was the final verdict on the heads? I did a search and really couldn't find much.

what kinda verdict are you looking to get??????
the heads are a really nice quality set and they flow really well

firefighter

performance... mainly how do they compare to a ported set of LS6 heads.

better runners for low end punch for sure over the ported ls6 heads...
plus they have a different vavle angle or something like that which give more PTV clearance..look at the terminators from TSP...

firefighter

I'm debating if it's worth buying them over having a set from an LS2 ported.

If you plan on using FI or even just a lumpy cam, the added strength of an aftermarket casting is a worthwhile investment IMO.

exSSer

Aren't those pretty expensive? About the same price as TFS, or ETPs, if memory serves.

a little less, but close yeah....
added strength is really a plus, but only if youre spraying of FI....i cannot see many members on this board overpowering the heads with their set ups...mine included...i went with some PRC 5.3's....

I think you have to be a fan of the smaller runner design. Throttle response and respectable torque, especially low and mid-range.

TSP version is 62cc. Nice bump in compression, right out of the box.

Erikthegoalie is right. A lot of different ways to achieve your goal.

Depends on what you are looking for..Smaller runners are fun on the street.

Hope that helps. Good luck..

well I'm thinking I want to make a strong steetable motor based on an LS2 out of a Goat I'm either gonna just put new rod bolts and pistons then call it a day or just put in a 3.9" forged bottom and just build a stout motor looking for AT LEAST 500/500 at the fly. I don't want a real lumpy cam or extra loud exhaust it's going in a S10 Blazer that is my daily with a M6. I would like to keep the cost reasonable thats why I'm not building a scratch 427ci and trying to get 700/700. The heads need to be good of course and I've allways been a fan of Edelbrock and Lingenfelter. But Dart/AFR/ETP etc. are not out of the question.

In the comparison that was done in GMHTP magazine, the Darts performed exactly the same and are less money. I have to admit to being disappointed in the Edelbrock results in that article.

firefighter

I can never find GMHTP I need to get a sub. The Darts also look promising.

firefighter

any other opinions? Also since I really don't know, what LS6 head is comparable to the Edelbrock/Darts? ETP what stage/Patriot what stage etc. ?

I wonder if the price of having my heads worked is cost efficient compared to buying heads from one of the mentioned brands.

The edelbrock head wasnt designed for a LS2 bore so the test was skewed..
They are working on a LS2 head as we speak,there LS1 based head is very good...

I'd verify that the intake runner has been updated before I buy the Edelbrock heads from TSP. Last I heard the intake runner doesn't match the Fast 90 intake.

firefighter

I don't necissarily know if I would use a Fast. It's alot of $$$$ I would at least use an LS6 but maybe one of the Aluminum intakes (don't flame me for that) I'm still trying to figure out exactly what I wan't to do.

I appreciate the info/opinions keep them comming.

Depending on whether you are more focused on streetable, daily driver power or trying to get AT LEAST 500/500 at the flywheel will make a difference. With 364 cubes, it will take more cam and exhaust than is really daily driver friendly. If you do go with more cubic inches, it wouldn't hurt to have larger intake ports. Your budget to get there will determine what works best.

Consider a short duration cam (220 - 224) with a tight LSA (112 or even 110) and either Edelbrock 202, Dart or AFR 205 heads for the best velocity & torque production. That should get you close to 450rwhp with a good exhaust, but you'll spend some money keeping it quiet.

Anymore news/reviews of the tsp terminator heads? Seems like only a few people have tried them.

edelbrock/lpe big port should be out soon.

Yes, but the AFR tested was the 205 and the Dart was also the 205 (based on valve sizes given in the article, not on them calling it the 225). The entire article was to some degree skewed, but I still find the Edelbrocks disappointing for the cost and power they produced.
