I considered it but I’m not that good at welding I would probly do more harm than good . I’m not sure what other options are available . I thought about jb weld but I wouldn’t want it breaking apart inside my engine .

The Procomps are definitely more cost. But once it’s all said and done (and paid for). Your not gonna look back.
I installed my pickup tube last week. It fits so loose and crappy I had no choice but to tack weld it. Can barely get the MIG to penetrate into the cast iron. I’m going to try putting the assembly on the BBQ in the back yard (lol) to get it heated up for more penetration before welding it.

Mine fit well too, it's just somewhere I saw a pic or vid of the pickup laying in the pan and the engine out due to oil starvation. Inexperience and paranoia prompted me to research retainers and finding none I saw some folks tacked welded the pickup, so I did the same.
Maybe it's not needed but I don't think it can hurt!

had to strike while the iron was hot and bought a set of b heads off a 425 cu 66 toronado very good shape with only 36000 miles on them.my plan now is to have them milled to 77cc's. originally i believe they are 80cc.and i will do a valve job and new valve seals .with the money i saved here could look at a roller cam ,lifters and rockers(we will see)i took this pic of the stamp number no idea how to decode it

Getting back on track with this build , i got a set of big valve e-heads ,they are at the machine shop now getting checked out ,hope i get better news than the last time! also went and picked up a rebuilt turbo 400 with a tci convertor for a good price .will be shopping for other parts soon and try to nail down my final selection on a cam.i was told these heads are set up for up to .550 lift ,but should i have the spring pressures checked in order to select the proper cam?or is there a way to determine exactly what springs are installed in these heads?

As for determining the exact spring on there, unless they are some type of recognizable shape or wire size, no, all you can do is determine what the existing installed height is, and the open and closed rate.
Depending on the type of cam you are going to select, you probably want to shoot for more lift anyway. Even on short duration cams, lift has benefits. At .550, I suspect they are for a HFT cam. Most rollers are over .600 .

Thanks for the advice I should have mentioned these heads according to the seller were redone and never ran , it appears to have all new valves , seals and springs ,so I would like to run them as is if they check out .

In a 355ci it has a lope, in a 455 it is pretty tame, works good with AC and power brakes. If you wanted to, you could have it cut on a 112 lsa to smooth idle a hair, but really not necessary.
You could probably get $75-100 for the springs if you eGay them, recouping some of the additional cost.

I dont see a TQ50 Olds cam listed in any of my Erson books back to 1999 The E545321 is not listed as a TQ grind. I will get in touch with someone I know who worked at Erson back in that time frame and see if he knows if there was ever a TQ50 grind for Olds.

picked up the heads at the machine shop yesterday and got them painted. waiting on the timing set so i can start putting this together .Question ,is there a time frame i should shoot for to get this all together and running ?i will use the cam lube and assembly lube where needed ,but how long can this thing sit around before firing up?

to answer my own question about how long this motor can sit around after assembly. months and months if need be! Now! on to the cam. got it installed today and started to degree it (first time i ever degreed a cam) its sounds simple enough, but without hundreds of dollars in specialized tools its a challenge. my cam card states a 106 center line and my numbers add up to 102 i assume this because the cam has 4 degrees advance ground into it already?? i will mess around checking lift and duration against the card tomorrow, if i can wrap my head around that process

so NO, thats is not correct i was doing something wrong ,and the centerline method i was using is not the best option .after a lenghthy conversation with Bernard Mondello i got this thing within 1/2 degree of spot on and im happy with that ,will clean up mating surface of the block and heads and install them tonight .consequently i prefer using a magnetic bridge and dial indicator to find absolute tdc,

Another question. When you degree'd the camshaft, was it off? Just curious because I degree'd two engines 20 plus years ago and they were spot on. I lent my degree wheel out shortly after that and haven't seen it since. Jmo, but it is usually the timing set that is off. Bill Travado has timing sets that are correct, probably other Oldsmobile vendors including Mark sell them. Thanks, Ken
