Hello guys and gals on my 90 iroc my cover gaskets are leaking I have the Is traditional blue rubber ones on there now Was doing some researching online.And found some cork felpro 1648 that will fit on tpi engines. I want to know if anyone has tried them yet. I know they are a little pricey but worth it if it works I will buy em
thank you

 

IMHO cork is an antiquated technology. The felpro blue is far superior

 

I just installed these felpro rubber ones on my 84 TA and am happy with them.
Was quite the project removing emissions lines to get the covers off!

 

I've been using those blue fel pros for years. I've been reusing them on multiple heads and valve covers. I've used the w stock valve covers and pro form covers. No issues w leaks. Obviously they can go bad and leak but I haven't experienced that in 15 yrs. I have 2 extra sets because the come w my intake gaskets.
