Please note

Listing in classifieds is for Paid Members. If you can't see the link to click to post an ad it is probably because you are not a paid member. There are no commercial ads allowed except by site sponsors. All for sale or trade ads need to have a price. No listing for offers only, but you can list something with a price. Ebay is allowed as long as there is a "buy it now". Potential buyers can inquire about the item being sold. If the sellers description has an error or not accurate you should PM the seller and or notify a moderator. No negative comments in the classified sections. We all have opinions, but we don’t need to bash people for placing an ad that doesn't agree with our idea of value etc. Members should be able to place an ad without worrying about being bashed. Members listing items or vehicles are expected to stand behind their sale or risk losing classified privileges and possible access to the forums. We want this site to be a place to be able to trust the person we are buying from. The seller & buyer are solely responsible for the terms and conditions of the transaction.

`70 LT1 SB Chevy 3927186 heads

Fresh from the machine shop is this pair of 186 small block chevy heads dated A18 and A23 of 1970. (January 18th and January 23rd)

These things have had everything replaced on them except the kitchen sink!

-Magnafluxed before ANY work was done

-Hot tanked and shot blasted, heads look brand new

-New 2.02" and 1.60" 1-piece stainless steel valves

-16 new bronze guides

-New GM screw-in rocker studs

-New GM guideplates

-3 angle performance valve job

-8 new hardened exhaust seats

-Guides cut for PC-style seals

-16 new KLine valve seals (far superior to the more common white teflon jobs most people install)

-New retainers

-New split locks

-New Z28 replacement springs (110 lbs on the seat, .520" max lift)

-Milled just enough for a clean-up cut (.006")

-Valve spring heights all set for correct spring pressure

-NO PORTING!

These heads are about as nice a set as you're ever going to find. No corners were cut building these heads!

$1400.00 + shipping.
