FMS you're a really swell guy; thanks for answering another question for me (cam plug)My newest concern is camshaft softness & reusing my existing cam in the new China cylinder head (an Amazon reviewer did this...)
My only engine photo showing the valve train, only the fuel pump cam lobe is showing..! The photo proves my engine has a hydraulic valve train; 135,800 miles now... I better measure Chinese cam journals compared to my existing cam (size matters..?)
TODAY: googled about camshafts; I will try reuse my original cam since the engine ran pretty fair before head/head gasket problem-oh...)
YouTube video https://youtu.be/PhyVb0dFK5c @ 6:22 (starts hardness testing of a typical Chinese camshaft & the results are not good...)
Not trying to bash Top End Performance: https://www.racetep.com/ but spoke with Steve there today and he said their cam billets are from either Turkey (very bad soft) OR mainland China (so so) or Taiwan (pretty good) when I asked about warranty he said he would not sell me a cam because I would blame their cam as the source of any future problem my engine might have..! Steve did confirm that these heads do not use cam bearings... Kevin at Clearwater said all these heads come from China & assuming since the cam is included it is also from China...
This [nice older guy] will regrind a stock cam for $250.00: https://elgincams.com/info/
Camshaft interchange part #s: https://www.yoyopart.com/oem/1228902...-md077306.html
Using the yoyo interchange info page; I phoned most of the companies selling these cams & NO body except Jegs Performance sells a cam for 1986 Mighty Max: (Melling cam with .040" over journals) Melling 1-800-635-5464 maybe they can answer if their cams are Made in China..? How does .040" over size jive with my fix..?
