Inliners International Forums General Discussion Blown and Injected Head gasket

What is the best head gasket for a turbocharged 250 @ 15 psi?

IDK, but probably Santucci gives a suggestion in his book https://www.amazon.com/exec/obidos/ASIN/1931128278/victorylibrary

I have Leo's book if you would like to borrow it. Lots of good info in there.

I have the 2002 edition of Leo's book - there are just two pages on the topic of head gaskets - and though one needs to read the rest of the book to put them in proper context, I will attempt to summarize.

He describes the Fel-Pro #8006 as "the workhorse" with no re-torq required on stock or mild hop-ups - but recommending re-torq in hi compression applications (greater than 10 to 1 comp).

He praises the newer design Fel-Pro #1025 and suggests that when combined with head studs "it all but eliminates the need to O-ring the block or head. It has been successfully used in supercharged and turbocharged engines in this manner."

If the build includes an O-ringed block then he suggests the Detroit Gasket #55002CS "is an excellent gasket for high horsepower applications."

He describes the reusable Clark and/or Specialty Component Engineering copper gasket as "really for serious competitors only and is almost always used in conjunction with studs and O-rings in either head or block."

He then mentions two other options: McCord #6889M and Filgar #G50005 (Argentia) with no particulars.

The book is a great read. An excellent addition to your library . . . or take up GMDad's offer and borrow it!

I don't think they were available when Leo wrote his book, but Cometic Gasket makes some high performance head gaskets:

I’ve purchased the second edition and read through it.
I’ve chose the Fel-pro 1025... supplier is going to take a couple weeks to get it in ☹️
Suppose I’ll be a few weeks from installing the engine, anyway.
Cheers!
