We have a 499 Indy head engine.On the Head gaskets what is the prefer head gasket. We notice on the Felpro 1009 gasket the water jacket bottom 2 center holes are not cut out on that gasket will this be a problem. I have seen most everybody says use this gasket.

I had problems with that gasket on my 505. Never really figured out why but trashed them and have run Cometics ever since. Zero issues since.

What kind of compression did you have also was your street or strip . Mind is Drag race only with around 14.1 comp.

One of the long standing complaints about the Fel-Pro 1009 is how close to the bore the fire ring is. I didn't have any problems with a 4.375" where there was basically no chamfer left at the top of the cylinders and the chambers were small enough to not leave the fire ring exposed anywhere. However, others posted about problems, including torching the tops of the block in between cylinders.

Is there a reason why you're not looking into an MLS head gasket, especially given the CR you have?

this is what I have in my engine right now. It was recommended to me to use rtv around all the coolant holes both block and heads. Birdtracker

That gasket is a little thicker than we want.

Get Cometics X2. They'll make the thickness You request, yes they are expensive but they work Great. 14:1 compression is not an issue. It will be a little higher along with a couple of other parameters with thinner gaskets so pay attention with the change.

SCE was one of the best gasket company out there when it came to getting custom made copper head gaskets for 3 of my blown hemi motor I built for customers up
They offer 5 or 6 different styles of copper head gaskets also scope
I say this based on past experiences before they where bought, sold again and relocated back east shruggy work

Think the holes your talking about are blank on the Indy heads.

No the Indy heads have the Holes as do the block but the 1009 gasket does not.

You will need to drill a hole a 1/4 or 3/8 hole in 1009 in the missing locations - at least that is what I have always have done with them if the head and block have the holes there

You need a specific deck and head finish to use MLS gaskets. I had a good discussion with Cometic about that and they are quite adamant about it.

At 10:1ish I would just use the garden variety Felpro that comes in their gasket sets. .039 compressed and the bore size is big enough to accommodate the chamfer without overhanging the bore which is the problem with the 1009.

If you need a thinner compressed thickness than .039 I'm not aware of any composites that spec less than that although I know of an instance where a .039 actually compressed to .037 and caused a hydroplane team to fail post race tech.

Depending on what thickness you need, although not recommended a shim gasket might be an option but an MLS is probably your best bet to get the thickness you require.

The only gasket I'd use in an engine like that is Cometic. Nothing else. The composite race gasket will work, but it will Brinell the head which ends up costing you money in the long run. Which is why I wouldn't use anything other than Cometic.
