I plan on getting vms's 1.5 cam and installing it myself, I cant afford a port polish head job from them but was reading up on doing it myself, it almost seems a waste to have the heads off and not de-burr them, port match and a polish. Ive been researching it and doesnt seem to be that hard. Has anyone did this befor or would it be a waste a time?
I've gasket match ported heads before with my Dremel tool and carbid tips but I've never messed with the combustion chamber or the valve seal area. Gasket matching isn't that hard and it'll pick you up a few horse's that for sure.
You're a little more advanced than the average DIY'er sir....
OP, FWIW the L92/LS3 castings flow so well that there has to be extensive amounts of work done to see a gain making it worth while. Even on the CNC'd castings I only see about a 25-30rwhp increase. All things considered those gains are acquired with a well thought out CNC program, valve job, etc. Simple touching up the heads with a dremel will yield little to no gains. If anyone wishes to debate that fact I'd love to see some solid data that states otherwise.
