I am trying to settle on a head gasket set for my car. 11:1 compression, zero deck, .040 over TRW flat top pistons with 915 heads that will be a street car.
Read all the posts I could find and for a .039" compression height (trying for quench here) it seems some are recommending the Felpro Marine Gaskets others insist on Cometic but the prices are quite high for my budget.
Not sure if I need the fire ring style gaskets for this or if they are good insurance?

Any help/suggestions would be appreciated.

I run the Marines on my 12.5 440 with Stealths.Put my old reworked 516s on the 62 300 with the 1009s.My 440 will clatter a bit under heavy pull with 93 octane.The 300 runs on it just fine.Rocky

I'd think a zero deck 440 w/ 915's would be a tad high thant 11:1 even with fel-pro's.
That said Fel-Pros.

How can you say that with the info he posted ?

I just ran the numbers assuming .040 overbore , 5cc valve reliefs, 80 cc heads and a 4.410/.039 gasket and get 10.55 , if the heads are 76 it's only 10.97.

Toss a bit more camshaft at it if the worry is dynamic compression...
I would love those numbers in a street car...

I was thinking they'd be closer to 76cc. not 80.

Planning to use a Hughes cam and springs at present (haven't purchased a cam yet.)
Here's what I am looking at:

HEH3237BL

110 LSA
Intake/exhaust duration @ .050 232/237
Lift with 1.6 roller rockers: .576/.584

I'll go ahead and order the Felpro Marine Gaskets part #17059.

I really appreciate the help.
BTW this is all for the car in my sig.

Mine must have been milled a bunch because they were 74. I though stock 906's were 84?

A good way to "guesstimate" the amount of milling is to measure the outside head bolt boss. Stock it is very close to 1.00 inch.

i'm using the HEH3742BL which is one up from the cam you picked, i'm running 1.5 ratio. very nice cam, i like it a lot. not super serious with my racing. i have a '74 challenger, 11:1 440, indy E-Z heads. 4 speed 3.73 gears on 28" drag radials. it usually runs 11.6 to 11.8 @ 118mph. probably could do better with the ET

I purchased the Fel-Pro Marine Gaskets #17059 after a mental struggle over the Mr. Gasket #5784.
Hope to have the CC number on the heads by Wednesday.

78 cc on the combustion chambers which I believe means they were only cleaned up not milled. Mopar Muscle article says the 915 heads were 78.5 cc stock. My stock 906s were about 88 cc IIRC.
