I'm looking at ordering a set of Pro Topline heads for a 91 Z28. Do I need to order angle or straight plugs to clear SLP 1 3/4 headers? I have sent e-mails to several vendors and even to Topline and got no replies. Can anyone using these heads tell me what you ordered? Thanks.

 

I ordered angle for my AFR but in your ase, YMMV

 

I think most people go to 90 degree plugs when they have headers. I would go with the 90 degree, they should fit in any case where the straight ones will only fit stock manifolds. If they don't fit, ill buy them off you

 

I'm asking about the style of heads, not plug wires.

 

i just put on the dart pro 1 aluminum 200cc straight plugs with edelbrock headers. plenty clearance. pics here at bottom. http://www.fl-thirdgen.org/mrr23/mrr23-18.html

 

Straight plugs fit just about every application. Angle plugs can be a headache depending on what headers you use.

 

angle plugs and slps dont work out to well. i have a set of angle plug heads and i have like 1/8 of an inch clearance on the headers with header plugs.get strait plugs i wish i did.

 

Thanks guys, Thats what I needed to know.

 

Where are you getting the heads from? Ive heard that many suppliers cant get the Toplines anymore, even Summit has none in stock.

 

I was going to get them from Summit, I didn't know there was a shortage on them.
