I guess what I am getting to is...if you spend all kinds of money building everything else to a certain level, it seems kind of senseless to suddenly develop a "tightness" at the exhaust ports? people seem to think nothing of spending 2 - 3 - 400 just for powder coating or a wee bit more for ceramic. WHY does it seem so weird or maybe not weird but "UN-frugal" to have the benefit decent long lasting well made exhaust? When I started this project I didnt really have the money for ANY OF IT. I saved, I sold stuff, I bought & sold stuff, I worked a few odd jobs, I found ways to pay for pretty much everything ( still have a few things to get like wheels & tires)...blue lines ( blue Streaks ) are around $600....the cragars are also around $600....and right now I don't have it....but I will find it & when the times comes I will have it. ALL of this hobby is prohibitive when you try to do it all at once. Simple answer I cannot do it all at once....for each segment I have had to build up the funds, this is just not a place or time for ME to get "cost conscious" ( too close to the finish)
