Question on angle plugs - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 1974 400 small block destoked to a 377. It has performer rpm straight plug heads. Im planning to buy some victor jr. heads which are angle plug. What is the difference and will angle plug fit on my block.

What they might not fit is Your exhaust,cast or headers.

running headers or cast manifolds? - i would hope headers with that HP level

You might have a tough time finding headers to fit. they make them for '67-'69 Camaros i think - supercomps

you might have to have some made depending on your application. regualr headers might work..but you will have to "dent" a few primaries to get the plugs in...and then the wire boots might be too close (burn)

use "shorter" "header plugs" to gain a little clearance

i had a set of original casting angle plug heads and nothing fit well but a set of RamHorns.
