Trick Flow 240s vs Bruce Toth ported heads

[w.Hudson]

One person who knows both heads and can give you the best recommendation for your build is Bruce himself. He’s a straight up and honest guy, just give him a call.

Bruce will be a wealth of info. He will go out of his way to help you with your build.

The member PRHEADS Dwayne Porter,, is who Y'all should listen to

Apparently, when TF was designing the heads, that’s the rocker they were using to determine the relationship between the rocker, rocker shaft saddle, and the valve tip.

That was my understanding..good to know it wasn't BS.

I didn't know that about the 'E' rockers. Cool

I am building up a 493 stroker for my 68 Charger. I'm going to be going with a Holley Street Dominator intake that has been deep gasket matched. Yes, I know some other intakes may be a little better but I like not having a hole in the hood. I have a solid lifter Hughes 242/248 @50 cam. I am trying to decide which heads to go with. Does anyone have any real world experience with either the Trick Flow 240 or Bruce Toth's ported heads? I know Mr. Toth has been at this a long time and is quite knowledgeable. There is very little cost difference between the two and every flow bench sheet I've seen favors the Trick Flows. I also know flow benches are not always indicative of real world performance and they vary greatly between benches, conditions, and operators. Any advice will be greatly appreciated before I drop upwards of $2k on a set of heads.

Buy the TF240 heads. Have you purchased the rotating assembly yet? Verify that you are going to end up with the correct compression ratio before you start spending money. If you are new at this then you need to double check all the math to make sure your pistons have the correct dish size in them to work with your cylinder heads and the deck height of the block. Ideally you want the piston to be within 0.005 of the deck so you can use a 0.036 Cometic gasket and hit 10.0 compression with the TF240 heads. If you do that then you'll have a very nice engine. Lots of people screw this up, don't be one of them.

TF recommends to use the Harland Sharp S70015KE rockers on the PP 240 heads. And they will work. But, after I checked how the rocker during a full rotation cycle it is not perfect. Spending almost $1000 on these rockers was disappointing to say the least. The roller sits too far to the exhaust side of the valve tip. Is it a big deal? probably not is what I have been told.

I did not use them like this. I spent more $$ to have shims made to raise the rocker shaft up and to the intake side of the head. Rocker geometry improved. Setting up the rockers correctly on the shafts with the shims became a tedious task. In the end the 505 was a beast.

I highly recommend the PP240 heads. They needed nothing right out of the box. The HS rockers not so much. There are better choices. Talk to Mike at B3 Racing Engines if you are serious about correct rocker geometry for the TF heads.

AND geometry correction for ANY brand of head, I had T&D rockers & he made the custom offset spacers for my 440 Source heads & the LIFT of my cam

you can see the offset shim, spacer under the rocker shaft

I built a 512 stroker for my 70 charger with a comp roller cam of similar duration and an edelbrock performer rpm and a quick flow 950 double pumper. I really the trick flow 240 heads. It is still pulling hard at 6000 rpm which means good flow. I went with the Hughes roller rockers. Be careful which rocker arms you order. The trick flow and edelbrock heads take different rockers than most other heads. They are a little bit longer from pivot point to the roller tip so that they are centered over the tip of the valve stem. Enjoy the massive TORQUE you're about to make.

Sorry, I said Hughes. I meant Harland Sharp. A bit pricey but worth it.
