Need a good head gasket for 14 lbs
I'm looking for a good head gasket for my 383 that will hold 14 lbs from a P-1SC. I did a search but didnt come up with anything useful that I could see. Thanks

Re: Need a good head gasket for 14 lbs
I just want to make sure that I go through this one more time only. If that means copper so be it. Isn't the 1074 the stock replacement? If so that is what I had on there last time, granted my heads were slightly warped but still I want to do this only once.

The 1074 is a thinner LT4 style gasket. The stock LT1 gasket is thicker & made of weaker material... do not use these. You should be fine with a 1074 & studs.
You will not see 14# from a P1SC either, unless you have stock heads & a small cam. Expect more like 10-11# max.

Avoid copper on a street car - they almost always seep. FelPro 1074 would be fine. The Cometic is an excellent gasket but to work properly the correct preparation of the head and block deck is essential - they must be straight, flat, and very smooth or the gasket will not seal properly.

I've used both the Cometic and the FelPro. I have not used the Titan gasket. It sounds good, but of course that is their own description. AFAIK they don't make one for the LT1.

FWIW the "stock replacement" LT1 felpro is 9966PT and is $17.97 from advance auto parts.

The 1074 OTOH is listed as "high performance" and will set you back $46.46 from advance auto parts.

The Cometic gasket I have heard wonderful things about when done right, but again - prep is key. If you search you will find that people have leaking problems because of the final surface finish of the head/block surfaces. If done right the Cometic will hold, but if its not right you are in for headaches for a while.
No matter which you do though, good studs will make a huge difference. Some have stuck with bolts and paid the price, despite everything else done properly.
