Random questions about PI Headswap....

[5spd GT]

So I hear the compression will end up being around 10.4:1...is there anyway to lower that slightly by use of a little thicker headgasket? I don't want to mess with quench area. I would rather not do any 'bowl work' to the heads either.

Also, I'm getting 02 heads (used) and stock PI cams, can I still reuse my valve covers that are on my 98?

What is this I hear about needing a new PI cam bolt? Do I need one?

Can you bolt the heads/cam together or do the heads need to go on, then the cam, then set it up?

Just some brainstorming questions...I will have more...thanks for your time!

you can use the 2003/04 Cobra head gaskets to lower the comp ratio, pricey at @$200.00 pr

you can re-use your cam covers, cams and heads can go on as an asbly

1998 back use a 12mm cam sprocket bolts(same as used on the crank) and 2001 up PI camshafts use a 10mm cam sprocket bolt, so you might need them.

if you go wth aftermarket cams, they use the 12mm cam bolt

So I guess I'll be needing the 10mm sprocket bolts, I hear they are expensive.

If I have 02 heads/cam, will I need a particular model intake?

I think I'll pass on the 200 dollar headgaskets, nice to know though

Just how important is the tune if I just do PI parts and nothing more. I'm keeping stock MAF, exhaust, etc.

Also, any power to be gained from PI to non-PI manifolds, because I'm getting some.

You can look at cometic headgaskets, and if you're going to stay n/a or nitrous you don't need to worry about the CR

really? $3.70 each list price is not that expensive

111,000 miles on the car and drive it everyday, and Yeah I was going to stay N/A. It is my daily driver.

So Randy I can come to you when I need all the parts/gaskets to complete the swap?

thats is correct about the parts and I have no idea what DB posted about, musta' been more parts then that?

 

[d98gt]

Yeah, The bolts weren't expensive at all. I bought them from Randy (along with the cam cover gaskets) a while back

not to steal the thread or anything, but with those cobra head gaskets what compression ratio would i be at, and is it dependable? :SNSign:

I have no idea, I just no some of the shops I sell to use the 03/04 Cobra head gaskets to lower comp ratio and have not see any issues wth them

 

[5spd GT]

With 02 heads, do I need a particular model intake like 01+ or 99+ will work?

Anyone know of the cheapest place to get a new PI intake with the aluminum crossover, tapped preferablly

 

[Dusstbuster]

Yeah I know the bolts themselves weren't that bad...although I don't know if Randy is quoting you with a "RANDY" price or the price you'd get if you walked into your local dealership and asked for the part. That $85 price I quoted was for the cam bolts, new heater hose reroute (which by the way I should specify was the wrong part, I got sent the hose for a Bullit so that may have affected the price too), hose nipple, and possibly some other part I'm spacing out on right now...the price also(I believe) included shipping and in-state tax since I got them from Tousley Ford in Minnesota.

yeah, I posted the suggested list price but I dont sell anything for "list"
and "yes" that Bullitt spec hose is @ twice what a normal one is, why didn't you call me

 

[Dusstbuster]

At the time I didn't know you also offered parts, or if I did it spaced my mind, and then I saw Tousleys ad on SVT performance.com and since they were "local" I figured I'd buy from them since they offered all parts @ 10% over list...unfortunately I forgot about the whole in-state tax. The next day shipping was nice though! I got everything worked out and ended up returning the hose for a full refund and found some high temp "rubber" hose that worked just as well and cost $10 haha. If that bursts I'll give you a call.

Randy I still love you...sorry
I'll add you to my writeup right now!

not a problem bro' just bustin' your chops

oh and that 10% over cost stuff, is alittle bit of sales hype as sometimes 10% over cost is actually more than 25% or 30% off of list price

 

[Dusstbuster]

Oh well, hindsight is 20/20 I guess right!?

Now I know for future reference
You're in the writeup now too.
