Best Valve Cover Gaskets for RA III Set Up?
I am seeing that there are different thickness valve cover gaskets, for our Beloved 400 CID Poncho motor.
Have a now rebuilt '68 WS motor, with #48 heads and RA exhaust manifolds.
I want the thicker gaskets for the valve covers, but I am not seeing on the net who is the best manufacturer, the part number, and who sells them?
In the old days it was cork & rubber, and that may well still be, but I am seeing newer materials being used.
I.e. neoprene, solid core, etc.
FelPro was the standard, but not sure if still is...?
Can anyone please provide me with the info I am looking for?
Looking to buy some now.
Thanks in advance for the info.
