1982 Chrysler New Yorker - Looking to increase compression on the 82 4bbl engine, which was barely 8.0:1. These 88' 302 castings should take us up to 8.9:1 no trouble… 1982 Chrysler New Yorker - Not wanting to borrow the valve spring compressor twice I'm removing the valve spring retainers/clips the old fashioned, dangerous way. Put… 1982 Chrysler New Yorker - Grasp the 13/16 inch deep impact socket and WHACK it with the rubber mallet. You're wearing eye protection and listening intently for where… 1982 Chrysler New Yorker - After a whack or three the first clip usually pops out 1982 Chrysler New Yorker - One clip remaining, watch your eyes and keep your safety glasses on and hit it again 1982 Chrysler New Yorker - There's the other clip, a little out out of focus. The deep socket usually captures the clip no trouble 1982 Chrysler New Yorker - There's the ages old original Mopar valve seals. The intake closest to us, the exhaust furthest away. Clean and/or file the edge off the si… 1982 Chrysler New Yorker - Exhaust valves were not that badly carboned up 1982 Chrysler New Yorker - They cleaned up well with second or two on the wire brush 1982 Chrysler New Yorker - Intake valves were pretty coked up alright. 1982 Chrysler New Yorker - Intakes cleaned up fine too, with just a bit more time. 1982 Chrysler New Yorker - This intake valve concerned me. It wasn't loose in the guide so I'm assuming it was a dead plug or spark plug wire. 1982 Chrysler New Yorker - It could be just the valve face not sealing well against it's valve seat in the head. Either way it's got some special attention coming it'… 1982 Chrysler New Yorker - What am I cleaning the valves with ? Just a wire wheel in the drill, clamped into th3 good old 6 inch Record vice. Takes a couple of second… 1982 Chrysler New Yorker - The valves MUST go back into their original guide, when you're lapping. Slip the seal on the valve, underneath, in case you tip the rack ov… 1982 Chrysler New Yorker - There's the course 120 grit valve lapping paste and the lapper on the lamp 1982 Chrysler New Yorker - More than a little impressed with the fairly direct shot these 302 exhaust ports have, compared to older 318 heads 1982 Chrysler New Yorker - Here's my valve lapping station using the desk lamp. You can see the initial course lap on the exhaust seat in the first chamber. 1982 Chrysler New Yorker - Fresh coats of 70s Chrysler Blue 1982 Chrysler New Yorker - The most vicious cleaner I could find to use to clean the carbon out of the ports 1982 Chrysler New Yorker - Even comes with a handy spray straw 1982 Chrysler New Yorker - Off with the old open chambered 82' New Yorker 318 4bbl heads part # 4027163. Plain 1.78 intake valves and chambers so large you barely ach… 1982 Chrysler New Yorker - Anyone who says there ain't a HUGE chamber volume difference between the open chambered heads and these closed 302 chambers needs his eyes… 1982 Chrysler New Yorker - After 30 years on the road....no carbon ridge on the cylinder bores and not too much carbon on the pistons. Cross hatching still on the cyl… 1982 Chrysler New Yorker - Cleaned off the pistons with 3M pads mounted on the 2" air grinder. 1982 Chrysler New Yorker - Gakets on and torqued to 95 ft/lb spec.
