Just finished take measurement for my TFS 215 milled to 61cc with Torq V2 cam 232/234
Here's what I got
Intake : .090
Exhaust: .209
Am I good to go or is it too tight?
Here's how I did it: measurement was taken using TFS springs, yella terra UL rockers and 7.5" push rods. I bolted the heads on driver's side with first cylinder on driver's side(closest one to radiator) TDC according to torque specs with ARp bolts, I already have clay on that piston. Spin the motor twice to get one full cycle(I marked the pulley to make sure I get 2 complete rotation) take off the heads, slice the clay to get the thinnest part of the intake and exhaust valve and get the numbers.
Any comments/suggestions will be appreciated

Had none of those when I did the measurement.
I'm almost positive that the valve will clear the pistons. I've talked with brian tooley prior to ordering my push rods and he told me that with 232/234 duration i would be fine.
But I decided to do the measurement anyway to get the rough idea and an estimate of the numbers.
Everything is back together now just need to add coolant and oil. I'll update when I have the car started tomorrow how it goes.

also with that chamber size were is your static compression going to be at?
what gasket will you use?
thanks
should be really nice, bad *** heads , and a nice cam

It's always good to hear what other people say. I'm sorry that I did not do the proper measurement. But I thought I post the result and I learned that without solid lifters or checker springs I can't get the precise numbers.

Finished everything last night, spent almost 3 hours to figure out why fuel pump wouldn't kick in when I put the car on ignition and all the light in the dash were acting funny.
Turned out it was one ground wire that should be bolted at the back of the heads was hanging.
Another thing that I found out the hard way(LS1howto doesn't even mention it) was ls1 heads are reversible and there should be a bolt that block the holes for engine temp sensor on one head since the other head will have the sensor bolt on. So coolant shooting all over rear passenger side engine bay...finally I moved the block bolt from the old head put it on the new head and all is good, no valves hitting pistons and my valvetrain is quieter.
Any idea how many miles before I can start beat on it?
