Installing cylinder heads
About to put the new AFR 165's on.
have read some of the head bolts need silicon on the threads "if" they
pass thru a water jacket.
Which head bolts do i need to put silicon on (if any) and which just need oil
for proper torque?
any other tips for head install?

RE: Installing cylinder heads
The bottom head bolts are the ones that go into the water jackets. The top bolts are blind so no sealant is required. Now you're going to want to use some moly lube on the washers and bolts also. After you're initial warm up let them cool for at least 2-3hours then retorque the bolts.
