man your asking alot of questions with no answers for having a motor that built. not to be a dick, but you got alot of trick stuff done, you should know all this already.

having said that:

If the car is turning over, i would do the following:

1) DO A VALVE ADJUSTMENT

2) TDC IS TDC, there is no difference with what cams or what crank you have. THe crank still turns the same number of times in relation to the cams. you could slap a 101mm crank in it, it wouldnt matter.

3) If you have spark, and you have fuel, then you need compression. since you stated there is no compression, i would do a VALVE ADJUSTMENT, check the timing belt.

4) I hope you have some sort of Chipped ECU or some form of EMS to start the car, an i hope its not a stock ECU your hoping will crank it.

5) Timing should be at 16 Degrees BTDC once it runs.

6) Helms manual will state what the valve adjustment should be, or 7 on the intake, 8 on the exhaust which is what we do.

good luck
