    First of all what kinda headers do you have?


    get shorty spark plugs...I tried the little kevlar socks that go on the spark plug boots, that you buy for like 70 bucks for a set of 8. They worked for awhile but then eventually turned white, and would allow the boots to get burned again.

    Ive been thinking about trying to route my plug wires under the headers instead of over the valve covers...... may want to look at that. i dunno.

    blown as in blower? what size is the blower?what size are the primaries on the headers? if they arent big enough they will get extra hot. are they the cheap hookers or super comps.
    a pic would help.

    you might have to get the shorty plugs and kevlar boots. blower motors tend to get pretty hot.

    its at least 1 5/8". thats the smallest they get for SBC. the super comps are thicker so thats good, but if they are either 1-5/8 or 1-3/4 they are probly bottlenecking caussing excessive heat, not to mention robbing horsepower.with that big of a blower i think you need alot bigger primaries.

    im no engine guru, but i know a thing or two. i'd say you need at least a 1 7/8". maybe even a set of BBC headers w/ adapters, tho i dont know how well they work. you can get BBC headers off the shelf w/ 2"+ primaries.

    wheres all the engine tech guys?

    Could your motor be running too lean with that blower? That will cause the exhaust to be super hot, and could eventually cause piston damage.

    What plug wires are you using now? I would recommend Taylor spiro-pro wires. I had one accidently lay on a header tube, and it didn't melt. Granted it was only like that for a short time, but I was still impressed.

    I've had problems with wire separators getting hot and distorting, and I found MSD's t-locks work best.
