Richard, i cannot answer directly, but hopefully will help. On my stock motor with headers and side pipes, i had to use a special socket to remove the plugs. When i pulled the motor and replaced it with my current 383 which had the Edelbrock Performer RPM heads with angle plugs it made plug replacement a lot easier. Not sure how the different headers will affect this though.
I'm curious on what responses you get on the intake since i'm using a Weiand Street warrior dual plane intake, holley 750 and a 14" air filter with 2" drop base. I'm interested in a different intake but the low profile hood of the 1980 may limit options.
i have angle plug afr's with dougs headers, fit just fine.
im using a victor jr intake with a 2.5'' drop base and it clears the 75 hood i have on my car, im pretty sure that sits higher than a performer air gap
I am running the straight plug version 195's with Hooker Super Comps 1 3/4" primaries. I have no issues with plug accessibility. Can't help you with the hood clearance. I am running a Dart Kool Kan with a 1" HVH super sucker spacer and Mighty Demon 750 carb. Covered with a L88 hood plenty of clearance.
A local engine builder is building a 383 stroker for my 1980 so I have a few questions:
For AFR 195 heads, if I intend to use Doug's headers, do I order heads with straight or angled plugs ?
For Performer Air-gap intake with Holley 750 double-pumper, if I use 2.5 or 3.0 inch drop base air cleaner, will this for sure clear stock hood ?
thanks in advance,
Richard
ON the intake/hood clearance question:
I have a 79 with modified with an '80 front clip and hood. I have at different times run the Edelbrock 7104 RPM Performer and 7501 Air gap RPM intake, all with a 2 1/2 inch drop base cleaner and a Holley DP.
Now I have a small block stroker, AFR heads with the 7501 air gap, a Quickfuel 850. I have adequate clearance for a 3 inch filter.
