After hours of searching for the biggest cam that would fit I've decided the hell with it and I'll be flycutting. Heads are TEA 2.5 LS6's and cam will be MS3 or G5X4. Wanna keep the compression over 11 so I'll have to go alittle thinner on the gaskets with the material being taken out on the pistons. Heads are milled .010. I've seen threads were .035-.040 was ideal quench, but seen several running the .040 gasket. What are your thoughts on the tighter quench?

from what i was told, cant remember who told me on here, but 0.033-0.035 is for race and 0.035-0.038 is street.

I've got .040 cometics with pistons out .006 and my quench is fine on a stock bottom end. I will say that engine will see no more than 6300 rpm, with my cam, no reason to go any tighter.

.027" Cometics, but .008" in the hole

You could always go right in the middle using a .043" Cometic to put you at .036" quench.

How high are you fellas spinning them? I'll be looking at 6800 shiftpoints more than likely. Spoke to Jason at TSP and he is all for the .040 so with the info from you guys that is probably the direction I'll head, assuming I can find the things! Keep the input coming! I do appreciate it.

I've run .040" on quite a few cars. I -think- I've even run .030" before (.023" quench cold) but wouldn't recommend it for most sane ppl.

lol........023 is close! I'll be calling the shop tomorrow Joseph to order up some parts. Round me up a fly cutter to rent! Jon said you guys are out of the rentals, so I'll have to buy one if not. Thanks buddy!

I may be able to find enough cutters to piece a kit together. Although to do it the right way you'd need a core head with the valve seats cut out for the cutter to cut at the right spot.

also consider as the engine warms up your quench will grow. (aluminum block expanding)
You will be fine with a .040

I have 40's, havent run it yet, but was told when I asked on here, to let the engine warm up as Brent mentioned before getting on it.
