Anyone have problem w/ .040 MLS Gaskets?
Looking at purchasing a set, just want to check to see if their have been any issues. I know ppl say to check the P/V clearance, where I should be fine w/ a 228R Cam.
On a side note: I'll be running a 11.34:1 CR, anything that I should watch out for there?

As far as the gaskets, I used Cometics, had them on and off twice and used them for spacers when cutting the pistons. I have around 600 miles on them after the second torque with no issues. I used AFR heads and GM bolts.

What octane will you be running? Do you know how much overlap there is with that cam and when the intake valve closes? You will want to be mindful of your dynamic compression ratio. You will need good a tune and to keep an eye on knock.

Also, I'll be running 92 octane.
What's the difference between Dynamic CR, and regular CR?

-----------------------
You can't be sure what gasket to run to obtain optimum quench until you remove the heads and measure it. Every engine is different. I did three motors from 3 different years and the deck height was different on all three. It's not much different but .004" is the difference between a tight quench that will help ping in a high compression setup such as yours. Again, you are already going to have the heads off so why not measure it.

I have 63CC and was willing to give up a couple of HP to be on the safe side. Im going to be running the stock GM gasket at quench . 051.
Ill be a hair under 10.9:1. With my baby cam, Ill be safe and not sorry. But I wont be shooting for 450 RWHP either.
I was only looking to be at 410RWHP. Just a little more fun, and not much extra wear on the car.
if its not right, gears next year
