This is a 400 block , 4.435 bore (.095" over) , heads are O ringed (B1s), CR around 13:1 , is it a simple matter of cleaning the old silicone off & applying some around water ways? , is it necessary to anneal the gaskets? TIA. Last edited by 602heavy; 03/07/09 08:19 PM.

What is te best place to buy these? i put mine in the oven at 300* untel thay turned blue,air cooled,scotchbrite and then lacquer thinner... there was a comment that as long as the gasket bends easy you dont need to aneal it. easy depends on the thickness i guess.

I can deal with that oven-prep .. but a rose bud ? .. !! Where do you get these, how do they work on a daily driver(and maybe even a motorhome motor) ? Are there any shelf-sizes and stock sizes ? ... or are they made-to-order ? ... to each bore size and thickness ? Got a list of places that have them ? ... THX
