Valve Tip/Rocker Height Question??
Thanks MRL,.
Teringer, I not complaining that loud. My 318 is a '69 which was overhauled before I bought it and had a mild cam installed. I measured the piston height when I replaced the heads, it had .039 gap at TDC. That means it's one if the higher compression motors. I wanted to go with better exhaust so I found a 340 driver's side exhaust manifold and also bought a passenger's side Mag truck 360 manifold. I already had 2 1/2 exhaust all the way back (with cross over). When I had the sealing problem with the mag truck manifold (the ports are much larger) I decide to go with the 302 castings to get a good seal. I ported the 302s and installed new SS valves. The engine already had a 600 Edelbrock and performer intake. So with the 302 closed chamber "ported" heads and improved exhaust manifolds I expected a good 20-30 HP increase. It runs well but still doesn't have the torque and power I'm looking for (3.08 gears). Maybe I'm asking too much. I'm in the process of installing a 2004R transmission into my Cuda (and switching to 4.10 gears) so that should help on the low end. It's just that now that I done all this reading at the FABO web site I realized that I never checked the valve height nor whether they were close to the same height. I bought a nice set of adj rockers for the 390 I plan to build and was wondering if the rockers might help since I never checked to make sure the 302 casting valves were all the same height. I guess I should have mentioned the mild cam in my first post but the question was strictly about using adj rockers to compensate for varying valve heights.
