where are you going to work now?? houston??

 

I have a set for my Vette. They are currently apart while I clean them up a bit and set them up for using Crane rockers. Best parts of these heads:

- 1 piece lightweight valves, intake is only 98 grams and is larger than stock and the stock one also weighs more

- Nitrided beehive springs

- titanium retainers that are only 6 grams

- machined locks that are only 2 grams

- 1 piece valve seal/seat

- decent flow numbers with room to grow later (several places are developing CNC programs for these heads)

- meaty rocker base that us stronger than stock

 

Movin to Austin AP.

 

Yes they area very nice piece. Alot people said you had to do alot of modification to get them on but all I had to do was grind the nubs off the rocker guide plate and everything bolted up fine no problem.

 

I sometime wish I would have got these instead of the patriots. I didn't know they have 2 different sizes available.

 

Got any flow numbers??

 

Dart has them on their web site. Go to new products, then LS1. At the bottom is a link to open the advertisement which has the flow numbers. 62 cc chamber will also bump your compression. Chamber is a little wider though, so a different gasket is required.

 

I am pretty interested in your thoughts of these heads. I am wondering what Richard at WCC may have in store for them

 

Sorry man I have so busy trying to get the damn truck running. I got those intake pics for you and Ill post them up tomrrow since they camera is at mjhowards house. They are VERY nice set of heads. They have all the edges filled down unlike the stockers that will slice ur *** open in a heart beat. They are very thick and well built they have ALOT of room to grow. The man to ask is mjhoward as I am new to the head game and he has years of experience looking at factory stuff and the very best of performance heads. he said he liked them and thought they were worth every bit of the price I paid for them. Everything that has been listed in the above post are dead on as to why I bought them. Hell I got my heads for a little over 1K and hell the damn titanium retainers are almost 200, stainless steel valves are close to 300 for good ones, valve guide seals are 30, the springs would cost 150, and locks are 15-20 so you can see that they are a very good value along with the fact they flow awesome out of the box and then have plenty of room to grow. I owuld definately buy them again if I had the choice of other companies. With the thick casting of the combustion chamber it would give Richard plenty of room to dial in the cc size of the combuction chamber for your radix app and they are alot more reinforced looking too. Ill post those pics for you in the morning Ill post everything I got of them on the cmaera there were a few that I didnt post

 

Just to provide a little more information, the valve seals will be more than $30 since they are the one piece seal/seat that GM introduced in later LS1's. They are actually quite expensive.

As for the Crane installation, I modified the valve cover boss because I also wanted my valve spring tool to fit for later valve spring change outs.
