I have decided to have the pushrod pinch in my heads welded so that I can switch to methanol. A couple of my friends tell me to get new heads since mine a so old and new heads would work better for me. I am bracket racing and ET isn't a concern of mine. The Sunfire runs in the 6.10 range and I am comfortable with that performance. I already need to purchase new shaft rockers and probably valves so the added expense is adding up quickly. What say you guys?

I use a set of Track1 heads that I bought in '97. The chambers are really slow and not very efficient. I wish I could upgrade to the Dragonslayer heads but it's not in the cards at the moment. They are a much better head and a good upgrade in my opinion. On my 383 it seems the heads are limiting me. I am on Methanol.

I have welded pinch t1’s
Run well
But it seems like there are better modern choices. Heck even raised runner or 18 degree

The T1 heads require shaft rockers, do most racers opt for heads with this type of rocker system or do you like a head with a conventional system? My old 355 ci from 1988 had Harland Sharp rockers with a junk stud girdle and just kept on trucking. But in comparison the old motor did operate at a significantly lower rpm.

^^^^^^ If you can justify/ afford shaft rockers they’re really nice. Curly said in another post the Crower SS he has are his favorite and I agree. I just bought a second set of Crower to match the ones I have on Brodix DS heads.

Canted Valve

The valve train in a pushrod engine is a weak link by design. Shaft rockers would bring you into today's technology and be a big step up in performance and durability. That's the path GM took with their LS/LT engine families. I'm certain you'd be satisfied but I'm kinda spending your money here. Your call of course.

I have run Yella Terra hybrid shaft rockers on my T1 heads for many years. That said no matter the brand the stability of shafts is always desirable over stud mount rockers.

A correction, the original Brodix Track 1 heads do not require shaft rockers. Brodix does produce some 23* heads with offset valves, which require shaft rockers. [Check the Brodix website for these details.]

It is correct that shaft rockers are a nice upgrade. I have built some engines with them and am always impressed by how they hold the adjustment over time.

Yet, I have also built many SBC engines with 7/16 stud rockers, stud girdle, and the proper length pushrods that hold the adjustment well. This is by far the most common, having won many, many, many, many races with excellent durability.

Also, the Brodix Dragon Slayer head is an economical, out-of-the-box excellent performer. The fellows at Brodix tell me they fully ported a 23* head, and copied it in an as-cast version. This is the Dragon Slayer.

Does anyone have experience with Scorpion shaft rockers? They do look nice and not priced to bad,but are they a good product? Thank you for your input

I don't have experience with Scorpian but here is another option for you that has a very good reputation with those who have used them.

I have an old set of Track 1s on my car. I bought them used and they came with T&D rockers but one of the 5/16" adjusters was broken. T&D said they don't sell them anymore but I could upgrade them all to 3/8". I opted to use 7/16" studs and rockers instead.

I have priced both T&D & Jesel sportsman aluminum shaft rockers. The T&D are about 450.00
more than the Jesel for my sbc. Are they really worth the extra expense?

Consider checking Crower for pricing on SS shafts. Excellent quality.

I've only ran T & D and not Jesel. I see no reason not to run the Jesel at the cheaper price.

Here’s the two items I did not like with the Jesel sportsman shaft aluminum kit I had for sbc. The stands are not notched for standard cap type head bolts. Jesel provides four flat head bolts that go underneath the rocker stands on each head. Jesel won’t service these sportsman rockers if they are over 10 yrs old and the dates are marked on the side of the rockers.

If you have offset valves may also require piston change or valve cutting.

Yes, shaft rockers are a good upgrade and I do think Crower is probably the best. I have used all of the big name brands. Have not tried any of the cheap ones though tempted as I have a pro street type car I only use a few times a year for cruising. Someone had a set of the cheap shafts and the shaft itself was cast and not billet or forged and they broke real easy. Total junk but do not remember what brand they were.

I'm still on the fence whether to have my vintage Track 1's repaired, or just buy a new pair. ?

Retainer failure.

Do I trust that the original valves will go another 1000 + runs?

Considering the pair I have need one cylinder repaired, will the rest of the seats be okay?

Have they improved anything that makes that the way to go?
