The pistons are fly cut for the intake and exhaust. I don't have the depth handy right now but they are fairly deep. As far as going for a smaller/less agressive cam, I'm all for that. I am just waiting on the measurements from my current cam to come back and then i'll post all I got on that and see where to go from there. and hopefully my heads come back inspection sat.

Car currently has SVO 30lb injectors running at 63 lb fuel pressure, 4.34 bars. The guy that tuned my car said he would retune after an injector swap for only around $50, since I'm already registered in his system. Can the current ones I have be sized up to 42 lbs? I'm not sure of the limitiations of this.

I don't know that FIC will resize the SVO. That injector is actually a 40 lb injector at 63 psi WOT.

Engine is 418, not LS2. Cam @ 231 intake duration is not unreasonable for 418.

your right that is not unreasonable @.050 duration for a 418 CID engine. However I think he was refering to the lift not the duration. Theres no need for the amount of lift this cam has with those heads. They just don't flow enough.

thanks for that... now I'm trying to find a price. Those would round my build out nicely. Plus, like stated, they would be better suited to my cam, therefore improving reliability, therefore reducing the chance of a repeat problem in the future and saving me money... So by buying those now, I save money. I love justifying necessities. I'll have to see if this logic works on my other half. But in all reality, those are some amazing looking heads and I have been told by my mechanic that the ones I have don't quite fit this build. I am waiting to hear from him today on the condition of my heads. If I did get new better flowing heads, could I get away with bare heads and recoup the parts off of mine? Or would it be better to sell mine assembled and buy assembled? See what you've started now...

Take a look at AFR heads if you want to change heads out. Your current cam is a nice rounded cam that doesn't favor hp over tq. Bigger isn't necessarily better on the street.

Another Excellent choice in cylinderheads if the mast motorsports heads are out of your price range.

TFS heads are also another good choice if the AFR heads are still a little spendy for you.

There's a fella near where I work that is semi-retired, used to work for one of the big cam co.s' and now does custom work for Nascar and private individuals and really knows his stuff. Cam Techniques, Sarasota , Fl. 941 727-5552. Good luck! P.S. To be really safe, you maybe oughta have the engine pulled and dissassembled for inspection as it may have further damage. Hope not, but better to be safe.....

That was it. No need to go above a .600 cam lift for 243 heads. They just do not flow at those valve lifts.

As of right now the engine is pretty much disassembled. It is still in the car but mostly on the shelves. The oil pan is being pulled next to see what is all in there. The rest of my cam most likely. I should have the exact numbers from my cam today as comp cams found the original order for the cam. As long as the heads are fine, they are going back on the car. I still have more research to do on heads and relationship to cam size, although once I get the cam specs I'll post them and am obviously open for suggestions/help. I want to drive my car again. It's 60-70 here and sunny. Plus I have my new TS front bumper to put on. I am going to try to get pics from my mechanic soon to post up. I'll see if I can get those up soon.

heres the passenger head with #6 cylinder covered in soot. the springs were damaged and on the seating surface of the head was damaged. the retainers on the springs appeared to be too small and on #6 the top of the valve that the spring sits on, the top was mushroomed out so it did not travel all the way. multiple lifters had wear marks on the roller part. and the cam has grooves and some deep grooves on most lobes. heres how it all looks....
