use yer 9/16 head bolts, push rods are same length and use tm115 head gasket.. will have to use some rtv sealant along the pushrod side as water jacket holes dont quite match up been running this setup for years ,,have yet to blow out that laminated steel head gasket?
Jim, Have you had any issue with the rtv holding the coolant? Any certain rtv? Was thinking of doing same deal with the 7.8 w/ gen head, but reluctant.
Thanks for sharing!
its just a small area on the pushrod side? for each cly. when you lay the steel head gasket on the block you will see the areas that i'm talking about? I did lay a short piece of thin o-ring along each spot too...didnt expect the ARP head studs would have much problem flattening them? One thing? if you are using a stock 401 water pump? you have to grind a bit off the front of the head for clearance?
