Excellent video, I would highly suggest a huge disclaimer though to check and scrutinize EVERY single new/replacement part, for example if you buy loaded cylinder heads, disassemble and inspect very very carefully. There are more bad/defective parts on the market right now than there are good parts, even high dollar name brand parts have been having alot of failure and quality control issues lately. Ever since 2020 parts quality and production has hit rock bottom, soo many common parts have became discontinued or put on an indefinite backorder with no guarantee of a restock. This isn't just affecting speed/performance parts, it has been difficult to even get normal parts for modern everyday cars and the parts you can get are absolute garbage, NOS (new old stock) parts are becoming extremely sought after and prices are skyrocketing. Right now it's hard to be a hotrodder and even harder to be an engine builder or a mechanic simply due to the parts not being available or dead right out of the box, hopefully things will turn around soon but currently all aftermarket parts are sketchy.

would be interesting to see a test of 1.6 rockers when this is complete on the dyno

[@Schlipperschlopper]

Always use 15W50 or 20W50 oil that countains between 1100 and 1500 PPM ZDDP and does not exeed API SF CD!

I would recommend longer studs and stud griddles... especially with that 3.48 stroke .higher rpms with studs dancing around especially mounted in aluminum.

[@oscarpuente2029]

very informative!!

[@Amack1964]

What rocker studs guide plates and pushrods where used

[@aliciaANDanthonySandoval]

Love this build

[@mikegillam1000]

Another great video! I can't wait to see what this does on the dyno

[@vintagedashboard6810]

I want to see how well it tests out afterwards. I’m doing the same but with a budget it’s taking me a while to get all the engine parts.

[@danhoy8356]

Great info! Glad I found your channel

[@MegaKencam]

Thanks Pat! I had been looking forward to this video.

[@Gearhead.327]

You did an excellent job of explaining how to set them up. Top marks!

[@87PontiacGP]

This is great info for when im done grinding my vortec heads, and having them milled at the machine shop. Thanks a bunch, great vid!

[@LJC5865]

Right on time..my 1st build and have the same bare block now waiting..definitely going roller with great lightweight cylinder heads needing to know understand how to check them. Was thinking the ramjet cam but will see how this turns out. Really appreciate you doing this.

[@tiffanybrantley7039]

This is very helpful. Thank you and keep up the good work.

[@hotrodswoodshed7405]

Absolutely SOLID great advice... I'm well aware.. but sometimes we need to hear it again for clarity. I'm building the exact same engine/head combo.. except with a .100 dome piston. And a oval track cam, solid 242/250 @.530 lift 106 lobe sep. For that mid torque saturation. In a street 1939 chevy truck

[@JoshF89]

Very informative, thank you for the video!

[@LeelandDomino]

[@donmilani129]
