I have JBA shorty headers that came with gaskets and header bolts. I will replace the bolts and want to possibly upgrade the gaskets as well since my mechanic want $500 just to install them. On stage 8's website they list this bolt set:

4.6 Liter Modular 8906 (16) 8mm-1.25x22mm bolts 6pt DHH

I have done searches and have found that some have found these bolts to be too short. Please help, I don't want to have to pay another $500 for a gasket change down the line. What are the best gaskets?

Use new OEM gaskets. The Stage 8 worked fine for me. Had to cut one down to fit in one place.

Don't mess w/anything else, trust me, I had to redo my gaskets and bolts several times. Three to be exact, and that includes dropping the K-member. Three times. What a pain.

Get the Percy's Dead Soft Aluminum gaskets from Summit Racing. They are GUARANTEED to never blow. They are awesome gaskets. They actually bend and conform to the headers/flange. The $45 they cost is well worth it.

Thanks, I got the bolts ordered. I will order the Percy header gaskets also. They also make a 2.5" collector gasket, should I order these as well for the JBA shorties to Bassani X pipe connection?
