ok so would it even be worth wild to port and polish 806 heads? Or should i just get a stock pair of 243 and throw them on? i want to do either a v3 cam or ms3 and i havent decided what to do with the heads yet!

Do what you will, but the 806's work just fine. I can't tell any difference between a "port 2" job on what people here term a better head, be it a 243 or whatever, and my 806s. Did the job myself.

Ok cause i know a few people selling 243 and i was just wondering

those are pretty big cams for stock heads imo, put some 243 heads on even for the compression bump alone.

Im leaning towards 243s maily for the reason i have an ls6 intake and the 243 are a perfect pair for it

TSP no longer produces a V3 cam, they replaced it with a V4 cam. I actually have 806 heads and am considering the same thing. Not to take over your thread but does anyone know if 806 heads fit on a 99 vette?

Yep 806 will fit in any ls1. Only thing is they have that specific valve cover and coil brackets. (pretty sure but not positive on the coil brackets)

I've had pretty good success with 806 heads. I still actually run them on my car. Ported intake side and good valve job made a nice difference. They flow about the same or maybe a touch better than a stock 243

If you can do the 243s for a good price I'd go that route instead. That's just my opinion

806's with any decent port work shoud outflow stock 243's. I don't think the MS3 is going to be anywhere near an optimal cam for your setup. It will probably sound badass with loads of overlap, but won't make power until high up in the revs, lack some serious torque compared to a more optomized cam, and will require a good tune (and large converter for automatics) to avoid bucking and surging.

If you really are set on this cam, I'd advise a very solid bump in compression, and a tight lsa.

I had Adavanced Induction port my 806's. Car made 408rwhp theu a 9" with a reasonable street cam. The 243's are a better starting point so with a full port & valve job you'll see greater gains with the 243's.
