Hi 1986F150six, No i couldn't find a block under .60 thousandths. I kind of gave up for the time being.
Decided to do a short run on the 460. Short run being everthing but the rings and head gasket.
Passenger side
Drivers side much less petty
Front
I still plan on a 300 I6 but i don't entend on resleving one. May be one day.
Re the 460 rebuild: The water pump front covers tend to rot away from the inside, creating leaks. Mine was. The aftermarket front cover I replaced it with has a much thicker wall in the area of erosion.
Hi Frenchtownflyer, i had some erosion but didn't think i was to bad. Someone had been in this 460 and it appears that thay had changed the water pump backing plate and timing cover.
I used Indian head gasket lacker on all the gaskets, a one piece oil pan gasket ect. Should have it in the truck by Saturday.

bullnose 1985 --- new to this 300 stuff and was going to do the same HD exhaust and Offy dual port setup. pictures look nice, was there any fit problems bolting it all to the head? I am using a 1992 heart shape chamber EFI head.
Hi old28, these are going on a pre fi head either of two i have collected. I would consider the offy "C" or the "DP". I am running the duel port myself but research in to both would be well worth your time and effort.

Thanks for the reply, I purchased a used DP this week along with a Clifford Valve cover. I really would like to run the HD exhaust manifold more for the looks. I know performance would be better with headers, but I like the old school cast Iron.
Hi Old28, Would love to find a allumum tall valve cover. I startpage.com for the HD manifold. If memory serves it came from Texas. Yes that HD manifold is a looker. Good luck on you're project.

bullnose1985 -- Thanks for the reply. Not a lot of the 4 1/4" tall Cliffords floating around these days. I have my head set up with two rubber valve cover gaskets and a 1/4" CNCdude spacer that will clear my 1.7 aluminum roller rockers & poly locks with a standard Clifford 3 1/4".
Word is that they are going to make a run of the tall covers in the next few months, but they are not cheep.
Hi Old28, i was wondering that the hight of the tall clifford covers were. Thank You.
I may hold out to see what the run Clifford comes up with. Good info thanks for that too.
