I have a pair of 99 C heads that I tore down and am bringing to the machine shop soon. I think I will need new exhaust guides and of course seats re cut and valves ground.
I planned to blend the cast port and the bowl machining myself. Only goal is to smooth the transition and round the sharp edge on the short side radius. I do not plan to "port" the heads nor do I want to pay for a full port job.
This is not a max effort build but I'd like to take advantage of any cost effective modifications while I have the heads off and apart.
I read about cutting the seat ID's larger but that seemed to be geared toward B heads. Do 99 tumble ports suffer from a small seat ID?
Any other ideas?
