I used a cast aluminum holly valve cover in the early 90's. The modello 7200 shaft mount roller rockers cleared fine. I was using the Engle 28/29 cam, it had 292° and 300° with .544 lift on both sides. The old holly ones did have a small olds symbol on them.
You can also make a plate with about 1/8th or 3/16th's in thick aluminum and glue a gasket on each side to add the thickness, yes it's a bit of work making them but will work.
i have a 455 olds in my 86 regal with stock valve covers its a tight fit Ive been wondering if any other valve covers would fit i want to say im around a inch away from the heater box everything stock besides intake
i also got edelbrock aluminun heads and harland sharp rockers in my big block. i got those oldsmobile sculptured covers, took the baffles out and they still do not fit. i think im gonna check it out again 100% before i get tall covers. i really like that factory look also good video and really cool shirt man!
Summit racing and rock auto have a good selection of oldsmobile V8 valve cover gaskets in different materials and gasket thicknesses peace and much respect to you hutchinson
I get my Olds valvecover gaskets from Competition Products in Oshkosh, WI They are a thick rubber with a steel core design, and they are like $14 a pair. I like em, no issues with leakage on any of my Olds motors.
I bought those same Chrome ones and didn't realize the breather whole location either. Horrible location. Also, the baffles inside those chromies look like they were spot welded by a 9 year old.

I used chevy BB rocker studs and HS S5003 rockers and my M/T stock size valve covers worked with a steel/rubber fused gasket and it all fit perfect.
The other problem, at least on my A body, was that the power brake booster has a clearance problem
The set with the offset breather holes is based on the 1966 Toronado 425 design not SBC.
Ahhh, I looked up some pics, and sure enough, that's it. You're right! But I still don't like it.

I got those raised lettered covers on my 75 olds 442,455 they look clean

Thanks. I'm hoping the BB covers will work. They're a little taller than the 73/74 covers.

Thanks!! I couldn't find any Olds shirts I liked, so I made my own.
I'd look for the mr gasket valve cover gaskets there were made of cork and are pretty thick I myself perfer the fel-pro # VS 13403 T PERMA DRY PLUS

them 5 bolt valve covers work very good on a stock valve train,no leaks
Mondello has valve covers that will fit. That's what I used.
It's more than just fitting the rockers. It's fitting the engine and A/C Box too. They also have to have a factory look for my taste.
@@hutchhiperf I get you. They're cast aluminum. They have the oldsmobile script. Check out their website.
@@israelalvarado1695 I know the valve covers. I've seen them before. They're nice, but not for me.
Stock valve covers fit over Harland Sharp rockers minus baffle
The old BB ones do. I'm going to fashion a thin baffle to cover the opening to keep the oil from being pulled out.
dude, you need long high performance baffles or you will be chasing oil consumption. High perf baffles are very long for a reason
I bought those same Chrome ones and didn't realize the breather whole location either. Horrible location. Also, the baffles inside those chromies look like they were spot welded by a 9 year old.
I was reminded that they're the Toronado style breather location. Still don't like it.
@@hutchhiperf of all Oldsmobile motors to model those after they chose the one with the lowest production numbers.....🤔🤣
prefer to use with baffle in center of covers
