gerg 10,871 Posted July 2, 2021 I hate those umbrella seals. Mine crumbled to bits after only a couple of years. When I got my heads done up, I got them to machine the guides to suit press-on Viton seals. Never had to think about them since.Sent from my CPH1920 using Tapatalk 2 deankxf and Outback Jack reacted to this Share this post Link to post Share on other sites

If I had my time over I would've yoinked the hypatec rebuilder pistons for a decent set of zero deck flat tops. 17 down the hole is a lot on a little 302Sent from my CPH1920 using Tapatalk 2 CHESTNUTXE and Outback Jack reacted to this Share this post Link to post Share on other sites

No wonder they were considered a slug. I wish I'd gotten on the bandwagon a long time ago and built up a good healthy streeter... I like nothing more than to see an orphan engine punching above its weight.Sent from my CPH1920 using Tapatalk 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites

Not the end of the world but you lose the advantage of actual open chambers with their unshrouded valves, yet don't have quench action like a proper closed chamber does.
