Default info on tfs heads??

Anymore info on these tfs heads, specifically the 215 cc ones?

Any clearance problems with the valvetrain or geometry problems (rockers)? Are new rockers needed?

Are these a true bolt on just like a stock head?

Why would one purchase the tfs 215's over the afr 205's?

pm Brian Tooley, he'll tell you all you need to know. I'll be purchasing these heads in a couple of months.

No clearance issues at all. TFS won't warranty the heads if roller rockers aren't used though. I think stock rockers wear funny on the valve tip.

They require +.300 pushrods. I think the rails are raised on one side so no modification is needed to clear roller rockers etc.

I won't answer that because my answer would be biased.

From everything I've seen and heard on here, new roller rockers are a necessity, not an option.

Contact Brian for the facts, but he did post recently that roller rockers are required.

Default Tfs

Some angle on the geometry of the heads is different, so you must have roller rockers. Most add the Harland RRs, about $350 for a set.

Contact Vengeance Racing or TEA for more details.

So, add another $350 or so to the price of using these heads then, right, when comparing to AFR's.

Don't ETP heads have built-in rocker stands that allow you to use stock rockers with them? I wish TFS would do that as well.

You'd better believe it...it's always the details that add up when doing something like this, but it is something that is so often overlooked. And yes, the ETP heads have rocker stands that allow you to use the stock rockers.

ONLY use roller rockers with these. You will need longer pushrods also, I'm using 765's. The upside is they make good power, as good or better then the AFR's. The harlens will clear the stock valve covers, but I had to massage the pvc baffle on the one to get them to fit right, not really a big deal.

Supposedly TFS will have LSX heads out early next year that can use stock rocker arms. Maybe Brian Tooley can confirm?

Heads aren't cheap($2400 for the TEA/TFS). It would need pushrods anyways(we all know the stock ones suck). Most of these people by fast 90/90 set ups. Harland Sharp rockers are about $350 and I would figure with the amount of money people spend on these set ups it wouldn't really matter anymore. They would want roller rockers anyways.

I agree 100%...but people get kinda weird when talking about money and cars. If they can't get a set of heads for under a certain amount, they usually start flipping out and going off on weird tangents about how people are spending too much money for heads when they could have gotten Patriots (not picking on them in particular, but they are a budget head) instead or had Joe Schmo port them, blah blah blah. I just like to make sure people have a healthy dose of reality before making decisions like these, cuz in no way is modding at this level cheap, and it seems like people try to make it out to be.

Could you give me some details on that? I'm in the middle of the install.

which part? Harlen's are a good option for the rockers, you need to check for pushrod length, 7.65's worked for me. The baffle piece on the inside of the cover just needs to be hammered a tiny bit to provide the clearance or the harlens will hit it, not too much. Is this what you're asking?

Good luck with your install

Yeah was just wondering. PCV baffle is on the passenger side right? Ok so just give it an old tap a roo? I'm using the pushrods that TEA sent me with the heads. They did all the calcs, stock motor, never been opened up (stock deck) with milled TFS heads (58cc) and I have 7.7" pushrods.

sounds about right, you'll know right away if you have the right pushrods, just torque the rockers to spec and youre good. I would put the cover on, turn the motor over by hand (or with starter, just pull the coils or something) then pull the cover off and see if there are marks on top of rockers, only two were hitting on mine, I don't remember if it was the front or back, but I took a hammer and just tapped it in a bit.
