just use machinest dye to check valves valve grind compound leaves a line- right but the valve gets bigger with heat and the line is no longer in the right place you are not building a model A or Chevy stoveblolt

rumble got it right several pages ago me- stroked 340 but wait- that's a 360 much easier parts availability and on the street cu in rule cast cranks do not break and are a lot cheaper than forged most power per dollar starts with a magnum takeout look at it another way and start with heads or...

you are fine 302s need more bowl and port work to make more hp

keep posting post cranking comp when you get it together and mech comp

Some truck/motorhome heads, marine, industrial

back to first post-- blue would not be teflon

not a318 hater it's $$$ to get a certain amount of torque now pick how much you want and sharpen your pencil

what you are missing are normalized seat durations looking at your list the clear winner is the shorter lunati just looking at how much shorter @.050 and the lift 340 cam would suck on a 8.25 motor- it's way bigger you want the best get mike jones 256@,006 cam has 460 lift that crower post...

do not lap determine valve or seat you can check runout or swap a different valve if it's the seat the whole head has to come apart if grinding using a cutter not so much I touch all new valves, od hone the stems and check runout chk the guide clerance seats etc

i'll take a look when I get back from the DR lunati is best choice for a shelf cam but which one

just pencil it out both ways just because you can do it does not mean you should A 360 magnum may be less expensive to buid even if you have to buy a core or just stick one in and go and do not use that cam even if it's free
