Keep an eye out on this site: www.racingjunk.com go to the search bar and enter 049 or 781 or oval... something like that. I would recommend getting a set and having a shop install new valves and springs so that you know that the right parts are in them.

racingjunk is the best and then ofcourse there is Egay. anything else? any good aftermarket oval ports u recommend

[Bumpstick]

Something no one seems to mention about oval port heads is... Be sure to have the machinest take atleast .125 off the top of the guides (if they are stock or replacements)... Oval port heads have different guides than the rectangle port heads which are already setup for high lift cams...

With oval ports and stock height guides if you go much of anything over .550 lift you will find your valve seals mashed and smashed and possibly bend a pushrod or two...?

Where are you located other than "at sea" just PM me I have several sets of 049`s & 781`s if close might be able to help you out...?

I got a pair of 781's from a pick your part for 140 with a 30 day warranty against cracks. Im also going back for a 9" out of an econoline with brakes for 180.

ive been watching ebay for a year looking for rectangle port heads and they keep selling for a grand plus!! but the good news i see 336781 oval heads like the ones i have sell from $50-$300 a pair and usually $60 to ship to your door. old dirty ones 336781 usually go around $100 a pair if that. and completely rebuilt ones with 2.19 intakes go up to $300 much cheaper than youd think and cheaper than having some rebuilt yourself!!

got the motor today. took me 1hr to tear it down and an hour to get it out of the truck and onto a stand (heaviest thing i ever moved by myself). here are some pics of the motor block #14015445 dated '81 heads were #346236 also dated '81 everything seems to be original. taking off the oil pan and having a friend check everything to see if its ok to use.

Looks identical to the 454 I bought while stationed in South Carolina except mine was complete with the carb, dizzy, ac compressor, alt, power steering and all brackets still connected. And the 400 tranny was still mated to the block.

These guys were trying to put it in an old Pontiac station wagon, said it wouldn't fit. I did't try to help, I just bought it!

Anyway how's the bottom end look? Good luck.

I have a 454 with 781 heads std bore ,8.25:1 compression and 561 cam. I dont know what it will dyno at but it runs 7.0 in the 1/8 on 87 octane and I can drive it anywhere. Now it does have a lot of head work but that is key to any motor. You can see my car and motor in my pics, I dont know how to insert them in here.

What kind of car do you have? I am in the proces of putting togather a 496 for a 1972 nova, and have been trying to get ideas from people what It may run. Here is my motor and car

496
fully ported 049's 2.19 1.88 valves
10:1 comp
port matched Victor Jr
comp solid flat tappet cam 248 254 @.050 .603 lift
comp pro magnum rockers 1.7
holley hp 950 carb
2 1/8" hooker comp headers with cutouts
12 bolt 355 gear & posi turbo 400 with a 3000 stall.

How similar is this to yours, other than the fact that it is a 496? I would be very happy with a 7.0 in the 1/8th.
