i help many people each day. Including in person. + repairing things. Makes itvtough when i have to push for info vs simply getting answers to my questions. :thumbs

You helpt me the most...sorry for not answering corectly.The spark plugs are BKR6E.Engine works fine i did not push him over 4000 rpm..How to figur aut what is the best heat range

You sure on that?
That's a 3/4" reach gasket seat plug.

MR43T Specs

80% sure maybe there is a nother letter after the E..But i bought the stock spark plugs for 502 cheavy...maybe the guy who sells them gave me the wrong ones...What does this mean are they too long or to short..

Pretty sure that SB said the long reach plug was correct for the 088 head
