Header fit issue

[ldr]

I used Hedman 66609 on my LT1 with straight plug heads. However, they will fit aluminum heads with angled plugs.
They are D port.

How are the plugs to reach with this header. I have GM fast burn heads with angle plugs. Hedman also told me they don't make a header to fit my Malibu with that head, but it fit yours.

I found the plugs easy to R&R with my straight plug LT1 heads.
Tightening the rear header flange bolts was a little challenging but they usually are on anything.

Are the LT1 heads square or D port?

LT1 heads have D ports.

Ive got a small block with "factory" iron heads and long tube Hedman headers in my 80 Elco. Fit with 0 clearence issues. I bought the cheap uncoated headers then had a friend of a friend ceramic coat them. Spent a total of about $300. What brand aluminum heads are you using?

they are a no-name brand from a seller on eBay. They're the fast burn type heads with square exhaust ports. Ports are all in the standard location.

the mounts are in good shape the mounts are in good shape they are the factory clamshell mounts.

I was just asking cause worn engine mounts can cause fitment issues with headers

I have an 85 El Camino with aftermarket aluminum heads. I installed SS shorty headers that have clearance issues with the frame on the driver side and upper control arm on pass side. I'm thinking about trying SS block hugger headers but so far everything I've found is for angle plug heads. Does anyone know if angle plug headers will fit on straight plug heads? I'm also open to suggestions.

Thanks to everyone who responded with suggestions and comments. I'm pleased to announce the header fitment issue has been solved. I got a set of Hedman # 68600 and they fit perfectly. I had to lift the motor up to get the old passenger side header off and while it was up install the new one but was able to install the driver side with it sitting down on the mounts. I think the passenger side could also be installed without lifting the motor up.
