Hey guys. I am currently putting new heads and intake on my 76 l48 350. I have e-street 5089 heads and and edelbrock performer air gap 2601 intake. My question is about the bolts. Edelbrock recommends their 8504 intake bolts. I believe they are 1" long. I have read that with the washer the bolts are actually too short. Does anyone have any input here? Just want to get the correct bolts.
I use and recommend the ARP 12pt. Intake manifold bolt set in Stainless Steel......the 12pt makes tightening easier on certain intakes and the stainless won't look like **** in a years time.....

I think your best bet would be to physically measure the thread depth of the holes on the heads. Some may be different. I have 1 short one on my BB.
Set the manifold and gasket in place and then use a piece of threaded rod, a dowel, etc to measure the length. You definately do not want the bolts to bottom out, while still getting good thread engagement.
I would also pre-check the threads in the heads to make sure they're all ok .
Definately use thread sealant on any holes that go through the head into the water jacket.
