Proper Holley Base gasket for 1970 454 LS6 ??
 

I need a Proper Holley Base gasket for a 1970 454 LS6?
Anyone know a part number or if Summit carries one?
Should it be a 4 hole or open gasket.
Please let me know before i buy the wrong one.
My Holley is a 4557 unit.

Its been years since I had the LS6 intake but almost positive it was open. Should be same gasket as 302 Z28. I just ordered one from Holly for the upcoming season. Can get the # if you need.

The Holly # is 108-10. I used the Fel Pro 60148 on my car for the past 14 years and just the last time I had the carb off I noticed the gasket was actually about 1/16&quot; smaller than the manifold opening all the way around. The Holly gasket fits perfect. Cost was $3 more than Fel Pro.

It's only $1.56.

I'm really not sure how Concours-Correct you want your car, but it might be a good idea to even consider the extra thick, heat insulator gasket. It raises the carb ub slightly from the the LS-6's pancake aluminum intake for a little more clearance uncer the accelerator pump while preventing vapor lock.

I may buy the GM NOS heat shield with gaskets in the near future.

Thank You Guys.
