Hello all, I am wondering how much I should be able to deck my heads on my stock 300 2bbl(iron heads) if I run 93 octane. I can't seem to find all the specs to find what my dynamic compression ratio would be with the stock cam. I burnt 2 valves(vacuum leak that went on a little too long) a little bit, and was thinking if/when I pull them sending the heads to have a little meat taken off to help performance some. I don't plan on hopping this engine up, but I need to have a reliable engine. If I pull the heads to grind the valves why not try to gain a little performanceo No:? Thanks guys.
I would have the minimum milled off the heads to clean 'em up, that's all. Your not going to gain much from milling a bunch off, unless you want to deal with intake bolt alignment, pushrods being too long now and lifter pre-load being a bit too much (requiring shorter pushrods) I'd go with a good 3 angle valve job, make sure all stem heights are equal, AND have the exhaust guides machined for seals, if Buick didn't use seals on the exhaust guides on the 300
Too bad you're not closer. I have a 300 Short Block with the Flat Top Hi Comp Pistons. Poston 110a Cam. PONCH
Ponch, I don't need the parts, but I would like to know the location of a good machine shop in the Saginaw/Flint region. Know of any? Thanks, DMT
