Machinist is finally gettin to the 250. Just in time I got the '79 Fairmont head from A1A in Lakeland.
He'll back cut the valves but when he asked about the exhaust I said I didn't know. Cost more? He said "no, & I'll do so unless U telephone me and let me know not to."
Again, all mods are to make this inta a lill tq monster.
1) What should I tell him about the exhaust valves?
He ordered a Comp Cam: 260, 440 lift, 110 lobe separation.
Will deck the block,
probably boar .030 (will be a 254 ci engine),
Moly top ring,
Re-grind crank,
lill machining to place vinton seals for valves (not umbrella),
"average out the comb. chambers" w/a machine (no hand smoothing of the bowls),
& all name brand internals (oil pump, bearings, gaskets, pistons),
the head will be ready to place on block when done.
2) Should anything be done differently for the '79 head? Weld up any taps, fittings, etc?
Thank you -
